B' L' (F' U L)
B L2 F' U // 9 4b2 2e
(F) F' U2 R2 {B U2 [R2 F]
R2 L2 B2 // 2E+S in 19 after removing B2

[] = F2 R2 F2} R2 F' // S in 22, BUT
{} = B' L2 B2 U2 // rewrite with blocky fish for slice in 21 and it's +0

Had to REALLY work for this one lmao. Had this 22 since like 20 minutes so decided to check the only 2+3 i wrote down on a whim after misscrambling something and got jumpscared by a ar-32 3p rzp, lol

L' B' R2 F'
R' (U' B2 D' L2 U' D L) // 12 4a1 4e
U2 F2 U
R2 L2 F2 U2 L2 U2 L2 // 21 E, +1, you can get slice in 20 from this htr but it's +3 lol

U' F2 B' R U
R2 B' D2 R F // 10 2c3 4e with 5c6e, cool
L (F2 D2 L F2 D2 L')
(U2 D2 F2 R2) // 20 M, +1

Mission failed successfully, cause i missed a free 21 from this by not switching F2 B2 L:
L F2 R
D' B D2 F U' F // 9 2c3 4e

Had this backup 22 since very early, tragic +2 slice, but this is opt from this variation smh:
L F2 R
D' B' D2 F U' F // 9 2c3 2e
(R2 D B2 L2 U F2 R2 D)
(R2 F2 R2 F2) // 20 E, +2 :(

B D R L2 U
F' B' U2 B' U2 L // 11 4b2 2e
(B L2 U2 D2 F)
(L2 U2 R2 U2 F2 L2 D2) // 23

Bad, had to submit a backup

Spent a ton of time on this, it has some 22s but they are really cursed:
(L') B2 F L'
(B) U B2 D F2 D2 F // 11 2c3 2e with 4 vars

Had this eo but missed the dr path:
L2 U F B' L'               // eolr       (5/5)
                           // rzpud-eolr (0/5)
B2 D R2 U L2 B             // drud-eolr  (6/11)
U2 F2 D B2 D' L2 U2 F2 U'  // fin        (9/20)

Missed this dr variation(didn't see it was +2 to trigger after B', ouch):
B' D' F' L'                     // eolr       (4/4)
B'                              // rzpud-eolr (1/5)
R2 D' F' U' F'                  // drud-eolr  (5/10)
U2 F2 U L2 F2 U B2 D2 L2 U' F2  // fin        (11/21)

Also there's this dr, but +2 rzp to 4c6e lol:
(D L2 B2 L')                   // eolr       (4/4)
(F' D)                         // rzpfb-eolr (2/6)
(B' U F2 D')                   // drfb-eolr  (4/10)
(F2 U2 R2 B L2 F U2 F' L2 B2)  // fin        (10/20)

Also TIL 6c8e has this 6mover through 4c6e:
F B2 L' (L')                 // eolr       (4/4)
U2 F'                        // rzpud-eolr (2/6)
U D B L2 F                   // drud-eolr  (5/11)
B2 R2 U F2 U2 F2 R2 U B2 R2  // fin        (10/21)

Lastly missed a couple of 22's cause i missed this 2+2:
B2 D (B D)                            // eoud       (4/4)
(F)                                   // rzplr-eoud (1/5)
B2 D2 L' F                            // drlr-eoud  (4/9)
L' U2 L U2 R' B2 U2 L U2 L2 U2 L2 D2  // fin        (13/22)

Bad solve overall

(L R') F2 B R'
U F U' D' B // 10 2c4 with 6c8e, nice
U' (D L2 D' B2 L2 D')
(L2 U2 F2 B2 U2) // 22-1

Cool dr, happy to have found this

Spent some time on this but thankfully didn't have to sink in time on checking reductions in 2 on variations on normal:
D B2 F' U'
B2 D2 R' B2 L // 9 2c4

While checking U/D normal 5movers i misscrambled and decided to prioritize checking the niss 3mover and inverse and didn't come back to checking them until after having checked literally all the other eos i had after getting the 21, and at 55 minutes i get jumpscared by this:
D L2 F R2 D
B' L B // 8 2c3 2e

Spent all the remaining time on this, but it's 21 optimal. However the +1 variation has a very free 20, would've found this 100% i if i had checked the eo with at least 10 minutes to spare and not 5:
D L2 F R2 D'                  // eoud       (5/5)
                              // rzplr-eoud (0/5)
U2 F' R F                     // drlr-eoud  (4/9)
R U2 L' F2 U2 R F2 U2 L R F2  // fin        (11/20)

Lastly there's this, which i missed because i straight up didn't niss trace after D, idk why, probably just forgot after writing a ton of extensions, but the 2move rzp isn't trivial so idk if i would've found the dr:
D' (L R' D')             // eoud       (4/4)
(F L')                   // rzpfb-eoud (2/6)
(F2 L' B' L')            // drfb-eoud  (4/10)
(R2 F' B' U2 F D2 R2 B)  // fin        (8/18)

A bit of a disappointing week in a sense that i would've got 22 21 20 if not for slightly bad time management, but oh well

(D' B L' F')
(U' F2 U2 D2 R' U) // 10 2c3 4e
(L' F2 B2 U2 R B2 R')
(F2 R2 B2 U2 D2) // 22

Found this at around 65 minutes, didn't switch the eo early enough:
(L D2 B' D)
U2 D2 B2 R B' // 9 4a1 4e
D2 F2 D2 F2 L
R2 B2 R2 F2 D2 // 18 E, +3

There's also this from the extension which i think is pretty reasonable to find:
(L D2 B' D)                    // eoud       (4/4)
                               // rzplr-eoud (0/4)
D2 F2 L' F2 U2 B               // drlr-eoud  (6/10)
D2 L' F2 U2 F2 R2 U2 B2 L2 B2  // fin        (10/20)

Other:
(L D2 B' D)
(R B2 R' L F) // 9 4a3

(F' B' L' D)
(R F B2 L B2 L) // 10 4b2 2e

(B L' F)
(R2 L2 U2 D R F2 L) // 10 2c3 6e
(U) R2 D B2 D
R2 F2 // 17 M+E, +1, +4 :(

Somehow this is optimal from all my drs, very overwhelming scramble

(B' L' F')
(L2 U2 B2 U' R) // 8 4a4

(B L' F)
(D) R' F2 D L' U' // 9 2c3 4e + ext with htr in 15 and slice in 21 on inverse but no VR's in +0

D B2 L' U
R (B' L B2 L) // 9 2c4

(B L' F)
D L' B2 R D2 R' U // 10 2c3 4e

This looks like the most reasonable 21, but i missed the jzp:
(B' L' F)                     // eofb      (3/3)
(L' U')                       // arud-eofb (2/5)
U2 F2 R2 U B2 U               // drlr-eofb (6/11)
B2 R' U2 F2 U2 B2 U2 R D2 R2  // fin       (10/21)

There's also a couple 20's, this looks like the most reasonable one but i didn't have the rzp for some reason:
(B' L' F')                  // eofb       (3/3)
L2 U                        // rzplr-eofb (2/5)
(L2 U2 L' U2 R U)           // drlr-eofb  (6/11)
(F2 R' F2 L D2 R' F2 B2 R)  // fin        (9/20)

(B2 L' U')
(L2 F' D2 B U2 L) // 9 4b2 4e
(B2 U2 B' U2 R2 F')
(R2 L2 F2 R2 D2) // 20 M, +1

Pretty much spend the whole second half of the attempt trying to prove there is a 20 from this dr and it's variation + 4 10move extensions, but apparently there isn't

Only other dr I worked on a bit before finding the 9+2:
F R L B'
L' D2 L' F2 L U // 10 2c3 2e

This is kind of reasonable-looking but switching rzp in 5 with 1 pair is tough on such a scramble:
(R2 F' L D)                   // eoud       (4/4)
(B)                           // rzplr-eoud (1/5)
R F2 R D2 F'                  // drlr-eoud  (5/10)
U2 F2 R U2 B2 R2 D2 U2 L' F2  // fin        (10/20)

D2 R' B'
U' D' L D2 L F2 D // 10 2c3 4e
R (R2 B2 L' B2 U2 B2 U2 L)
(U2 L2 U2) // 22 M, +0

Really happy to have found this one of 2 optimals on this dr, the other one is 3 half turns to trigger on inverse

Other:
R2 D2 R' B
L (D' L2 D L) // 9 2c4, unique 6q 22 opt lmao(had a backup 23 here)

R2 D2 R' B
L (L D L D2 L) // 10 4b3

D' B2 L B
D R' U2 R' U R // 10 4b2 4e, 23 opt

Completely missed this somehow, i have (U' R2 U...), (U' L2 U...) written down for the R F2 R variation which isn't correct. I think what happened is i did (D' R2 D B2 D2 L2 D) on the cube for htr but wrote it down as (U' R2 U...), and then undid (R2 U) instead of (R2 D) and instead of finding the 21 i tried (U' L2 U L2 D2 F2 D) which isn't a real htr:
R2 D2 R' B
L (L D R F2 R)
(U' F2 U R2 D2 B2 D)
(U2 B2 R2 B2) // 21

Could've also found a different 21 if i had switched the 4a2 4e reduction but the one above is about as free as they get

This is the only 20 mallard gives so the 21 opt from 4b3 would've been scramble findable optimal, sad:
(U D2 R F')                 // eofb      (4/4)
U' D                        // arud-eofb (2/6)
(U2 F2 B2 L2 D)             // drlr-eofb (5/11)
(B2 R B2 R' D2 L F2 L' B2)  // fin       (9/20)

(L' U2 D R)
R2 F2 U' B D' F // 10 4b2 2e
(L2 D2 F2 U' L2 D')
(L2 U2 R2 B2 R2 F2) // 22-1 E, +1

Mallard gives this 21 which is kind of findable, i guess? I saw 7c8e with ar-6c3e and switched immediately, didn't look at additional rzp, but looking at it now if you try (F) and notice it's 4c6e the rest is pretty reasonable
(L' D U2 R)                     // eolr       (4/4)
(F)                             // rzpud-eolr (1/5)
(B2 U D2 B' L2 F')              // drud-eolr  (6/11)
(B2 L2 D2 B2 U F2 R2 U' F2 U2)  // fin        (10/21)
Solution (21): U2 F2 U R2 F2 U' B2 D2 L2 F B2 L2 B U' D2 F' B2 R' U2 D' L

L F2 U D2 L'
B R2 F2 D' // 9 4a2 4e
L2 U2 F' D2 F2 R2 F'
D2 L2 D2 L2 B2 // 21 S, +1

Annoying scramble, a lot of stuff to check and short drs but all bad subsets:
(U' L' U)
(B D2 R2 B2 L F) // 9 4b5

D' B D'
B L' R2 B2 U2 L' B // 10 4c4

L F2 L2 F'
L2 U' F2 U' B2 R // 10 4c4

L B2 F' U' R
D B' R2 B' R2 B // 11 4a1 2e

D L' F' D
B L' F R' F2 L // 10 2c4

(F U' R2 F')
(R) U F2 U F2 L // 10 2cx 8e

(U' L' U)
R' L2 F' U2 B' D2 R // 10 2c3 6e

Should've found this dr(i saw jzp on inverse but didn't switch), but all the 20s are 5q, 21 is quite doable tho, and i don't see any other findable for 20s from mallard(edit: of course LMR found the one with 1 to 6 switch eo lmao):
L F' B2 U' R'              // eolr      (5/5)
(D')                       // arud-eolr (1/6)
L2 D2 F2 U                 // drfb-eolr (4/10)
B U2 F U2 B U2 F U2 L2 F'  // fin       (10/20)

R' F' B' R'
(D') D B2 R2 U // 9 4b2 4e
D2 B (L2 F)
D2 L R' F2 R L // 19

There was actually a 4q 18 from the exact variation i actually switched before having the 19 but i didn't check 4q fuuuuck:
R F' B' R'
(D') U R2 F2 D
(F' U2 F D2 B U2 B)
(D2 F2) // 18 S, +0

Returning to this after finding the 19 was probably not worth it but i absolutely should've found this when switching the dr before checking for niss htrs on the variations from the other eo, such a skill issue, idk why i didn't even check if there were +7 paths with 4q

(D' L B' L' F')
F2 B2 D' R U' // 10 4c3
(U2 L B2 L') D2 L2 D2 B2 L
F2 U2 D2 R2 D2 // 24, optimal from dr smh

Such a fucked scramble. This was my only sub11 dr, there is a single findable 23 from variations of this but you need to switch +2 4b2 2e reduction from the right variation on normal:
(D F' L B)
(D) R2 L D F2 R2 D // 11 2c3 4e + 11 4a3 var if you don't do jzp

Other:
(D L2 B L F')
(L' B2 L D L' U) // 11 4a2 4e but fucked, the other variation is 2c4

(R') F R U' L
(B2 R2 D B D F) // 11 4c4

(F' B' D' L' U)
L2 D2 R' B2 R F // 11 4b5 that looks like +3 to htr, sad

I don't see any other reasonable sub23s from mallard except for this but i missed the eo smh:
R' D' B' U' F'                    // eofb       (5/5)
D'                                // rzplr-eofb (1/6)
L' U2 R F2 D                      // drlr-eofb  (5/11)
L' U2 R' D2 L' D2 R2 D2 U2 F2 L'  // fin        (11/22)
