Missed a free 21 off this even though I had the htr and the 2e+slice in 19 but I had a brainfart and missrecognized that 2e was on the wrong axis. It turned out that doing 3 fmc attempts in a row after sleeping 5 hours last night wasn't a good idea :o

Other DRs:

I spent so much time on these variations, seems like 22 is optimal

Other DRs:

(L F2 B' R)

So many promising things and I couldn't beat the free 21, I'm bad :(

Other DRs:

U' D B'

(R2 L U' R)
(F L2 D F U) // 9+3 2c6e

Quite a few other promising drs but I don't think they were sub21able

Two cool 21s:

D L' U2 R'
(B) D U2 L2 B U F' // 11+2 4e, premove abuse and +1 ext
R2 B2 D' F2 R2 U' // HTR (17)

and

(R) B D B L'
B' F2 U F' B2 D // 11+3 2c4e
R2 B (U2 F R2 F') // HTR (17)
(R2 B2 U2 D2 B2) // finish (22-1)

Other DRs:

(D2 B2 U2 R2 L2)] // slice (24) but 21

[] = D2 F2 U2 L' F2 U2 D2 R D2 L' // solved (21)

Lucky ofc but not forgetting about switching all my rzps paid off.
Firstly I did (L R B2 D L D') // 12+3 2c2e and (R U2 R' U2 R' D2 B2 U2 R2) // slice (21) but I believe it's +2, then quickly checked the other variation and the htr in 17 was this "extend the htr trigger by M2 to get finish in 3" shape 

Other DRs:

F L U' R B'
U, L' R' D // 9+4 2c and U' L' R' D variation, spent a lot of time here but only found a 23 to slice

(U' R' F L D)
U2 B2 L2 F' L // 10+2b 2e, missed a 22 here idk how

(F2 U' D L D')
(F D2 R' F L) // 10+3 2c4e and inserting B2 before R' F L gives an 11+1 4e with 22 to slice, 

L' F B R B
R2 U' F2 D R // 10+4 2c

F R' D L' F
L R' U F2 U' // 10+4 2c

(F') F2 U' B'
R (L2 D F2 L) // 9+3 2c4e

(R2 U2 B2 R2 B2)] // slice (20)

[] = B2 R2 B2 U2 R2 U' F2 D' U2 R2 D F2 // solved (+1)

Bruh the only rzp I forgot to switch is the one with an easy 18 nice

I was spamming 5q htrs on this cause 1q 2e is often 5q optimal but there's no sub20 from this jzp

(F2 U' B2 [U R2 B2 D) // HTR (17)

[] = D B2 L2 U' D2 R2 // solved (+1)

Yeah I found it this way instead of just +6-2 to slice from an htr in 14 on normal lol

Also had another 19 from (R2 F2 R2 B', F2 D L2 U' L')

(B L U F2 D')
(L F' R2 U2 R' F) // 11+0 4e
D2 L' F2 B2 R // HTR (16)

(L U' B R)
U' (B2 [U R2 U2 B2 U]) // 11+2b 4e
D2 {B R2 B' U2 B' U2 B} // HTR (19) + double slice 

[] = U' B2 D2 L2 U' // +0
{} = F D2 B' R2 B' R2 F // +0

Really happy that I found optimal from this variation hell.

I don't know why I didn't have (F B) B' L' F eo that gives 20/21 but not sure if I would've found the dr anyway

Other DRs:

[] = B' U2 B' U2 F U2 B' R2 F' B2 // solved (+1)

Once I got this dr and saw the blocks I finished it immediately so the rest of the attempt was just fishing for a dr with sub20 potential and it didn't show up :(
