Gave up halfway through the attempt because I had to go

F2 R' U2 F'
R (F2 U2 L' D2 L)
D2 L2 B2 U F2 L2 U'
D2 R2 B2 D2 F2 L2 F2 // 24

(R' U2 B D' L')
(R2 F' R2 U) // 9, 2c3 4e
B L2 U2 B' U2 B
U2 F2 R2 F2 R2 F2 U2 R2 // 23 eh

Pretty eh considering the DR

Had the HTR for the unique 21 opt but did not find the double slice smh

F U R L' D'
R (R2 F' B' U2 F B2 L) // 13, 2c3 2e
F U2 F' U2 F'

+1

What

(D) F' R' D
(L' U2 D2 L' U2 L) // 10, 4c3
(B U2 B U2 F2 R2 F) 
(B2 L2 U2 F2 D2) // E (22-1)

+2

Pretty eh 

Edit: Did not know to check the variations, man

(F2 U2 B)
(L' U' D2 L' D L') // 9, 2c3 4e
U (F2 U B2 R2 B2 L2 U')
(F' B' L2 F' B) // Slice (22)

+1 :skull:

I had too many good DRs to only get a 23...

I did not whack the HTRs on the 8 to 4a2 4e well enough, another big miss again...

dont do fmc sleep deprived

U (F B2 D)
(F2 L F2 R' F' R) // 10, 4c4
(B' U2 F) R2 F' D2 F'
R2 D2 R2 U2 L2 F2 D2 R2

Well, that was shit

(R' D F B' L')
(B U) L2 F2 B2 R2 U' R2 U' // 14, 4a1 4e
R2 L2 D2 B // HTR (18), 15 to HTR did not give anything for me
R2 U2 R2 B2 U2 F2 // Slice (24)
F2 U2 B2 R2 B2 U2 F2 L2 // Blocky Fish for different Slice (24)

+1

Did not find anything decent

Casually missing 3 move setup to the trigger, how very typical

(F' D' L F')
R L F2 R D // 9, 4b2 4e
(R2 D2 R) U D' R2 U' D L' // HTR (18-2)
F2 L2 B2 U2 R2 D2 // Slice (22)

+1

Missed the normal setup to the trigger for an easy 21, missing easily findable triple 21 for 24, 21, 23 is pretty skull...

(D2 B' R D)
L' U2 L' B U2 B // 10, 4b2 2e
F2 D2 L' F2 L
B2 U2 F2 L2 D2 L2 // ok (21)

Had this as leave slice first but you just needed to widen everything so why bother writing this out. Weird kind of sprint scramble. Now I'm angry that I missed the first 21.

EDIT: How does everyone know 3c4e. I actually played around with that exact RZP for a couple of minutes but did not find the setup, sadge.

Not bothering to check optimal on my 9 to 4c3.

Mallard finds a 19 by extending R (R B R) to R (U2 L' B' L) and gets a 9 to 2c4 +10, nothing I would find.

U' R' U' F'
R' L2 D' L B2 L // 10, 4b2 4e
(U2 L2 D' R2 L2 U' L2 U L2 U)
(B2 R2 L2 U2) // 24

This is 22 opt, but I don't think I'm able to find the unique optimal for this. Weird scramble, had 53 EOs but almost had no RZPs. 

Also missed a 21 from this because I did not find the right variant:

U' R' U' F 
D F2 L U2 R L2 D // 11, 4b2, missed the variation with the 21, even thought about possible variations but missed it anyways smh

Also this was almost possible:

U' R' U' F
(U2 D R) // JZP (7)
U2 R // E-Slice edges are in the wrong place for this to work smh, but subset is bad anyways

Stopped after 45 minutes because eh

(D' L)
(F' U F D2 F2 U2 B D) // 10, 4b2 6e
(R2 D2 L2 B U2 F)
(U2 L2 F2 R2 B2 D2) // 22

First thing I tried, did not find anything better afterwards, got lazy.

I fucking hate sprint scrambles

D' (F' B2 D')
(F U2 R F2 L' F) // 10, 4b2 6e
R2 U2 L' D2 R 
U2 L2 B2 U2 L2 B2 L2 B2 // 23 ugh

Did not try 4q because I was too overwhelmed in trying to find any solution at all. Not necessary in the end because the 22 DR optimal is from the exact HTR I used, but the finish destroys basically all premade blocks from the HTR and is just way too unintuitive to me. Maybe switching after HTR would have helped but eh. All those short blocky HTRs but they led to nothing. 

EDIT: Turns out I am also too bad at spotting quarter turn leave slices, Rogo found the other optimal that uses it.

D (F' B2 D') (R' F2 L D2 R2 B) // 10, 4c3, 23 opt, looked at it briefly and concluded it was shit
(U) F R F U' / D2 F2 R2 F2 R' B or B2 L2 F2 U2 L' B // 11, 4a2, 23 and 24 opt, did not look at those

Typical sprint scramble. I switched F2 R2 F R, which gives 4b2 in 11 for 21, but did not see the DR. Welp.

U' R F D'
R' ([F' D2 B2 R]) // 9, 2c4 4e 
D2 B U2 B' L2 F U2 F // HTR (17)

From here, I was at 56 minutes and the finish looked bad, and I had nothing. I still tried whacking the variation:

[] = (F' U2 F2 L) // (still 17)
U2 L2 U2 B2 U2 B2 // Solved, phew (23)

Optimal from this variation, 22 is DR optimal. Started working on this DR at 47 minutes and it turned out to be pretty tricky to figure out. +1 from optimal is pretty good for having 13 minutes for 2c4.

The other variation that I discarded is 22 optimal and requires switching after the first qt, which I did, but I did not invert the DR move on the other side, so I missed it. Idk if I would have found the leave slice from the HTR in the time scramble anyways, and solving the slice would have been a pain in the ass. 

Also I had the 21 opt 11 to 2c4 from the 0c0e RZP on normal but eh no.

U' D B'
D B2 D' R U' L // 9, 4b2 2e
R2 F2 B2 U' R2 U
F2 R2 B2 U2 L2 D2 // Slice (21), widen everything to solve (rare +0 4b2 slice, tho not really)

I have the feeling I missed something very easy but this is the only optimal from this DR. 

Edit: seems like everything looked better than it turned out to be, I'm glad I had the 4 variants of this DR in mind and didn't miss the easy optimal :D still waiting to see someone find some deranged 20 or sub-20, there is bound to be.

All my DRs seem to be 21 optimal at best, the only other notable DRs except the 3 other variants of this one are:

(L' U F) L' D (L D' R2 D) // 9, 4b2 6e, both variants 21 opt

(U L' F) (L2 U D2 R L2 D2 R' D) // 11, 4a1 4e, this has 14 to HTR but it's eh, has 21 to E but it's bad

Also only managed to check 9 out of 45 EOs that I wrote, misscrambled too much and there was too much to check on the short ones.

Good start into league

B (D' F R' B)
D F2 L D2 F2 L'
D (U2 R2 U' R2 U' R2 U)
(R2 B2 L2 F2 L2 U2 B2)

I somehow missed the 23 from the linear 2q HTR...

Edit: I'm pretty bad at spotting setups to the trigger from 4b2 6e when there is U2 parity, did not see that you could setup the trigger in 3 moves from one of the variants of this DR...

Edit 2: Ok I'm double bad, had the exact RZP that Brian had but did not see the 3 moves to trigger, what a waste of 21.67 :(

DR in 12 moment, miscounting the 10 to 4b2 as 4b5 didn't matter anyways

(U R' L2 D')
(L) L2 F' R2 F' D2 F' L // 12, 4a1 4e (this was JZP with 3 pairs but it was shit)
U2 B2 L2 ^ B
F2 R2 D2 R2 // Slice + 2e (20)

^: L2 B2 U2 B2 L2 D2 F2 D2 // Slice in 22

+0 because of the F2 B in the solulu

Unique optimal for the DR and the variations (those were 4a1 6e/8e), every other variation is some 3q or 5q bullshit anyways

Also I miscounted the 10 to 4b2 as 4b5 thrice, what the hell

Got trolled by the 4b2 4e

(U F R2 L' D')
(F2 B' L B2 L')
(B2 U2 B D2 L2 F')
(U2 F2 L2 B2 R2) // 21 to fucking doomed E Slice +4

Also missed the DR that Brian had somehow, even though I had the RZP written down, rip

F (U' B R' D' F2 D' F2 U R) // 10, 2c3 3e
D2 R2 D R2 D R2 L2 D2 F2 L2 U' L2 U2 // 23, Slice
 
+1

I'm mad rn, don't talk to me

11 to 4b2 moment

U' F2 L' D'
R' U2 F D2 F B2 L // 11, 4b2 6e 
(U2 B' L2 F)
(B2 U2 R2 F2 D2 L2) // 21-1

This is effectively 19 to slice +1 but I found it as the direct finish at first. Had a 10 to 4b2 6e that I looked at first, but turns out I mistraced parity and it was 4b5, so this was the next best thing I had.

Just 4b2 things. Same solution as my mallard.

Fuck

(B D2 L) // EO (3/3)
B (U' B2 R2 U D' F) // DR, 4b2 6e (7/10)
(R2 [U' L2 D')] // HTR (4/14)
(B2 R2 U2 L2 B2 R2 B2 R2) // Slice (8/22)

[] = (D' B2 U') // Solved (+0/22)

Man. 21 opt, I believe I had the HTR...

(L' U' F D) 
R B2 L2 B' L2 D2 B // 11, 4b2 4e with 8 variations 
(F2 L) R2 B2 U2 D2 R' // HTR (18)
D2 R2 U2 F2 U2 // Slice (23)

+1

There is a single unique 22 from one of the variations with 4q. I was looking for DRs up until 45 minutes and did not find anything decent, so no chance to find it

Miscounting the DR be like

(R2 U') // EO (2/2)
L2 F (R F' R2 F') // DR, 4a3 4e (6/8) miscounted it as 7 lol
D2 F2 L (B2 L F2 B2 U2 R) // HTR (9/17)
(U2 B2 R2 U2 F2) // Slice (5/22)

+1

Mismanaged my time because of that, had a lot of good DRs, so pretty bad result

(L) B L' 
U' D' F' D2 L2 B // 9, 4a1 2e variation hell
F2 U' R2 F2 B2 U R2 U' 
B2 U2 R2 F2 L2 // 22-1

Missed the 20 tho, did not check the HTR path off of F' U2 R2 F, tho I'm happy with 1 off optimal on a variation hell scramble.

Had a 22 at first that I miscounted as 23 and did not expect anything better, so I got somewhat lazy in looking for better stuff, so it's good that this popped up in the last 10 minutes randomly.

This is ptsd material

(F2 R2 B')
(D L2 U' L') // 7, 2c3 4e
(U) R2 U' F2 R2 L2 D 
B2 U2 L2 B2 L2 // Slice (19)

+1 for final

Missed the unique 19 optimal again, this DR in 7 shit is just out of my realm it seems.
I almost forgot to check the EO so at least I did something right

U' (R' B' U) 
B' U2 L2 F' L // 10, 2c4
(R2 B D2 B) F' L2 F
R2 U2 L2 U2 B2 U2

That scramble is a load of barnacles

D' R (B' L) // EO (4/4)
(U [F D2 B U2 B'] L2 F B2 U') // DR, 4b2 4e (10/14)
D2 F (L2 B) // HTR (4/18)
(R2 F2 D2 R2) // Leave H-Perm (4/22)
(R2 U2 D2 L2 F' L2 U2 D2 R2 B) // Solved (10-4/28)

[] = B R2 B L2 F' z2 // Leave 4x (0/28)

(...{F' L2 U2 D2 R2 F' B} D2 R'...)

{} = (B' D2 R2 L2 U2 z2) // BIG CANCEL (-2-3/23)

What a solution, should have probably found it more linearly...

U' L U F' // EO (4/4)
L2 F2 D R D' R // DR, 2c4 2e (6/10)
(U2 L2 U^) U^' R2 U^ R2 U^ // HTR (8/18)
L2 F2 L2 U2 B2 // Slice (5/23)

^: w // Solved (+0/23)

Last minute slice insertion, phew. Optimal after DR.

Also had this, found nothing better than 23 to slice tho:

(D) U' B' U
(R' D2 B R F') // 9, 2c4
(R' B2 R' F2 U2 L' U2 L) // HTR (8/17)
(D2 L2 B2 U2 B2 L2) // Slice, idk if +0 (23)

And it looks like this is also at least 23 optimal because nissy gives me some weird EO extension for 22...

So from my DRs (had another 23 opt 11 to 2c3 4e), there was nothing better than 23...

Found the same solution twice (optimal after DR) but the first I found was unnecessarily complex.

U F2 R' B' D' // EO (5/5)
F' B' L' B' // DR lol, 2c3 4e (4/9)

1)
L^ (D2 R^ D2 B2 L2 D2 B2 U2 R) // HTR (10/19) was just trying to solve the case and this happened
(D2 L^2 D2 R2) // Slice lol (23 but actually 22)

^: w // Solved (-1/22)

2)
R B2 ^ R (D2 L) // HTR (5/14) much more normal, but also found the HTR starting from normal
B2 D2 F2 R*2 U2 B2 // Slice + 2e (6/20)

^: B2 R2 F2 L*2 F2 R2 // Slice (6-4/22)
*: w // Solved (+0/22)

Had nothing else to work with so at least I found optimal for it.

(U) F2 B' U' // EO (4/4)
D2 L2 B L2 F' // DR, 4c3 4e (5/9)
R ([R2 B2 L' B2 L) // HTR (6/15)
(R2] B2 R2 F2 U2 F2 D2 B2) // Solved (8/23)

[] = (L2 F2 L' F2 L') // Downsize (-1/22)

One hell of a scramble...DR is 21 opt but idk.

(R2 U' D2 R' D) U2 B U2 F' U // 10, 4b2 2e is 22 opt but I did not see the 4 moves to trigger.

So many juicy RZPs and I went away with nothing at all

B' (L2 F') // EO (3/3)
(R) U2 L2 U' R // DR, 2c3 6e (5/8)
D F2 U B2 R2 L2 D' // HTR, I always forget that this trigger exists (7/15)
F2 D2 F2 L2 U2 // Slice (5/20)

+1 of course

Tired solve, so this is fine. Did not know how to handle the variation hell of DRs I got, so I'm glad I could circumvent it with this DR. Looks like you can extend the trigger by 1 move to get to HTR in 16 and solved in 20 (or switch and do the 4 HTs on the other side). Did not look at anything except this and the next DR.

Other:

B' L D R2 F (L' D R U) // 9, 2c4 (22 opt, looked at this briefly; fun fact nobody needs to know: DRU means digital rectal examination in German)

B' (L2 F), (L2 D) F2 U R2 L2 D // 10, 4c3 (23 opt)

B' (L2 F), U R F2 B2 U2 R2 U // 10, 4c3 (23 opt)

B' (L2 F), (U2 L) R2 L2 D // 9, 0c4 (21 opt but yeah why would I look at this)

U (U2 B2 R' D) // EO (5/5)
(U2 F' B R' B L) // DR, 2c3 2e (6/11)
(B U2 L2 B D2 B') // HTR (6/17)
(D2 R L B2 R L) // Solved (6/23)

No cancellation, sadge. Optimal after DR. First thing I tried and it decided to just be solved. Tried a ton of other stuff afterwards but nothing worked. Had not much else, so still happy with 23.

Other:

U' L' B D 
(R2 B R2 B2 R F R2 F') // 12, 4a1 6e (24 opt, looked at this for a really long time)

U2 R U2 R // EO (4/4)
B (U' R2 L2 U' B') // 10, 4a1 4e (6/10)
(F2 L2 F2 L2 D') // HTR (5/15)
(L2 D2 L2 U2) // Leave S (4/19)

+3 of course

Optimal after DR, +14 for 4a1, typical

U2 R U2 R 
B U2 F2 L2 D2 F2 D' B // 12, 0c0 (23 opt)

(F' L2 U' D2 F')
(R2 U D L' U2 L) // 11, 4a2 (24 opt, this was my backup: (U2 L2 U B2 U2 R2 U, B2 R2 L2 D2 R2 U2)

And then 2 4c4 in 10 (24, 25 opt) and a 4b2 4e in 11 (idk).

Damn...

(U' F2 D)
L B L U2 B2 L' F' // 10, 2c3 4e but it's so doomed
(F2 L B2 U2 L D2 L')
(B2 D2 R2 B2 D2 R2 D2) // Slice (24)

+0

Good start wow, this shit is 23 opt

Edit: ok how did I miss the 9 to DR 

(R2 F L U') // EO (4/4)
F L' F2 L F' L // DR, 4b2 (6/10)
(L2 U2 F D2 F') // HTR (5/15)
(B2 U2 R2 F2 U2 R2 B2) // Solved (7/22)

Unique optimal of the DR. Damn.

Really shitty scramble but doesn't matter if there is one singular good DR. Only found 26 EOs, NISSed the 3 mover and every 4 mover and only workable DR I had was this. I missed 5 of the 16 4 movers, so there's that.

Mallard only finds a 22 on my settings, so let's see what the others found...

(D) L2 F R U' // EO (5/5)
(F2 R' D2 B2 R' L F) // DR, 4b2 2e (7/12)
L (D2 R) // HTR (3/15)

I did not find the 8 move finish (U D L2 U D F2 B2 R2) until after the hour for this. Instead, I did this under the hour:

(...F') // DR
L (B2 U2 L') // HTR (4/16)
(D2 L2 U2 D2 F2 D2 F2) // Solved (7/23)

What a scramble...checked 61 EOs and this was somehow the only thing I had. Optimal from this DR variant, but the other variant that goes (F2 R' U2 F2 R L' B) for DR has a 22 somehow, even though it looked worse to me. I tried the HTR I think, but the finish wasn't obvious to me unfortunately.

There's an 18 from 0c4 in 7 lmao, ain't nobody finding that

B L' F U2 R
(U2 F' B' U2 B D') // 11, 2c3 4e
(B R2 F D2 R2 F) 
(B2 D2 L2 U2 F2 L2) // Slice (23)

+0

Did not have the time or the mental capacity to find the path for the 22, which is unique optimal for the DR, because I started working on this at 50 minutes again, smh.

Even though we are getting all the 2 move EOs, this was not easy. Somehow Mallard only finds a 21, using the EO I used of all the ones there are on the scramble, but finds a 12 to 4a1 with a 9 move finish, wow.

Other DRs:

(U2 F' D) B' L (F' R2 L2 F2 B' R) // 11, 4b2 4e, only had a 24 to slice that was surely not +0 (23 opt with a 4q path that I almost checked the right way, but only almost)

(L) F2 B' L 
D (F' R2 F' B2 U') // 10, 4c4 again (24 opt)

Ok I'm crying I thought this was a 24 wtf

(U2 R F2 D F2 R2 B' D') // 8, 4c4
D2 F R2 B (L2 B2 D2 F' U2 F) // HTR (18, not 16 bruh)
(U2 D2 L2 F2 D2) // Slice (23)

+1

Had this solution early on and somehow miscounted it being a 22, wtf. Had a ton of DRs but they all had high qt subsets, can't wait to see what I missed again

(D R U R F) // EO (5/5)
R' B2 D R' U // DR, 4c4 (5/10)
F2 L' F2 R (D2 L2 B2 L U2 L') // HTR (10/20)
(B2 D2 L2 D2) // Solved (4/24)

Pretty depressing stuff, can't wait to see what I missed. This is optimal after DR though, which is nice because I started this during the last 8 minutes. I had these as well:

(L) B D B L
U B' R2 B' D // 10, 2c4 (23 opt but I did not find anything except a 25, looking at the paths I would not have tried them)

(L B' U' D L)
(U) D R2 D' F2 D // 11, 4c3 (25 opt T_T)

L (R' L' B R) // I had the RZP, but did not find the DR in 11 for 23, nor its extension for 22

(R2 D' B R)
F D R2 D2 F D2 F' // 11, 2c3 2e
U' R2 D' R2 B2 D // HTR (17)
R2 B2 U2 L2 B2 R2 // 23-1

R U2 R // EO (3/3)
(F U) D2 B R2 F' U // DR, 4c3 6e (7/10)
(D2 B) D2 R2 B U2 B // HTR (7/17)
R2 F2 L2 U2 F2 // Slice (5/22)

+0

Checked 60 EOs and in the end used the very first I looked at, wow

F2 U' D' F' U (D2 R' B2 R D) (10, 4c3, 23 opt)
U (L U B D) (F' U2 R2 F B2 L) (11, 4b2 4e, 24 opt)

This one just straight up imploded, looked like I had good stuff and nothing worked in the end

(R B L2 B L) D L2 U D B2 D F // 12, 4a2
(F2 U) L2 F2 R2 F2 U' 
F2 R2 F2 R2 U2 L2 B2 D2 // 27 :(

Missed a +5 to slice for 24 during the time scramble, pretty depressing
