(D) B' D' L2 U
R F' L' B R2 L' F' L // 13 0c0 6e

obviously the only way to get opt off this 13-move dr is to UDFB shift it for +6, hard to miss honestly
(and yeah ofc you need 4q for opt+1 thanks for playing)

(D L' U B' R)
(U2 B U) B2 L2 U' R2 U // 13 4b2
this has +4 to htr and I found a few slices in 24 but didn't get the +1 in time

([U D]) L R' D'
B L F R' F // 10 4b2
R // 1q
[] = (R2 U D)
(B2 L2 U2 D2 L') // 17 htr
(D2 L2 B2 D2) // 21 slice +1

opt from the variations

U2 B R F, L D F2 R' D' R2 D // 11 4c3

I hate 4b2 4e

R' B' L' U
L R2 B R2 F' R' // 10 4a1
(L2 U2 L2 B) // 14 htr
(F2 D2 L2 F2 B2 U2) // solved 20

(F2 L U) L F' R2 F' D2 F R // 10 4b2
(B2 L2 U' B, U' D' L' D2 R D) // 10 4b2
(F2 R2 D B, U' D' R' U2 L U) // 10 2c4

22 to slice and 23 to slice, both +2 lol

miscounted this as 24 but didn't have better anyway

(U L D' R2 U')
(F2 R' F2 B R' F') // 11 4b2
U2 R' B2 U2 B2 D2 L
B2 D2 B2 R2 F2 R2 // 24 slice +1

only other dr was the +1 variant of this from inserting D2

(U' B2 R)
F2 U2 L2 F' U // 8 4a3
(B' U2 B' D2 B2 U2 L2 B')
(R2 B2 R2 U2 L2)

(U F2 B' U', F U2 L2 B' R) // 9 2c3

(F D) R' D
L B D2 F2 L F' R' // 11 2c3
(B) F' U2 B2 D2 L2 D2 B
U2 R2 D2 B2 L2 // slice 24 +1
forgot to check the variation of this dr which looks easier but both are 23 opt

(L' B R' F B, U L' R D L D) // 11 4b3
(D L F' D R), U2 D2 L2 B D // 10 4b3
(B R B' L' F, L2 U F2 U2 D R) // 11 2c4

B2 U2 D2 R
(U' F2 R2 U' F) // 9 4a3
(D2 F2 U') D2 F2 R2 L2 U' R2 U'
F2 L2 U2 L2

54 eos literally not a single sub-12 dr

U' D2 F R B'
U L' D' R // 9 4c3 miscounted as 4c4 until very late
panic finish 24 slice +1

miscounted this as 21 rip

L' D2 F' U'
(R2 B2 L B L) // 9 2c3 6e
(F' R2 L2 D2 F' U2 F)
(R2 D2 B2 R2 L2) // 21 slice +1

other:
(F R F D, R F L2 F' L) // 9 2c3 bait, also 22
(F R F D, R L' F' R' D2 R) // 10 4b2 21 but it's unfindable
L' D2 F' U' (F U2 B2 L B L) // 10 4a2 2e bad

8 4b2 +2 slice

scramble too bad
