Results

L F D' B2 R D' F' B2 D' F U L2 D R2 F2 D B2 D B2 L2 F2 D2 F2 D2 F2 D2

L F D' B2 R // EO, 3c2e (5/5)
D' B2 F' D' F // DR 2c4 (5/10)
U L2 D R2 F2 D B2 D // HTR (8/18)
B2 L2 // 2e + slice (2/20)
F2 D2 F2 D2 F2 D2 // fin (6/26)

imagine getting 2e2e and the insertion is just +6

But wait, there's a one-move-shorter HTR finish:
… D B2 D' // HTR (18)
F B U2 R2 F B U2 // fin (8-1/25)

Optimal from DR is +13/23:
nissy-# solve -t 24 -o R' U' F D2 R2 F U2 B F2 L2 D2 F' U2 F' D2 L U' R D' B2 R2 B D' R' U' F   L F D' B2 R D' B2 F' D' F

U B2 R2 B2 D2 F2 U' D2 B2 R2 D R2 D (13)

D' F2 L2 U F2 R2 U F2 R2 U2 L2 D' F2 (13)
L2 U B2 U2 F2 D L2 F2 L2 F2 D' L2 D' (13)

I guess it's just skill issue because the first three are just reduce to 2c3 2e then immediately switch;
no reason I couldn't have found those HTRs.

Also had these other DRs:
L B D' F R
B D' U F U D // 4b5 in 11, opt +14/25

(B2 L' D')
L F
(L D2 B R2 B) // 4b5 in 10, opt +14/24
(imagine how tilted I got when the first two DRs I found were both 5q)
(imagine how tilted I am right now when their optimals are still better than my final result)

L D F' U2 L
(D2 B' D B' D) // 4b2 4e in 10, opt +11/21
I didn't check this one very hard because I couldn't find a short HTR but uh, skill issue.

Unique optimal finish uses 4q:
U2 B L2 F D2 L2 B' R2 U2 B' R2

Attempt 2

Scramble

R' U' F D B' D R' U' L2 F R B2 U2 R L2 U2 L B2 U F' R' U R' U' F

Results

R' B D F D' R2 U D B2 D' R B2 U F2 D' B2 R2 U' B2 U D2 R2 F2 D2 L2

R' B D F // EO, 4c4e (4/4)
D' R2 U D B2 D' R // DR 2c4 (7/11)
B2 [D R2 U' F2 L2 U' F2 U'] // HTR (9/20)
R2 F2 D2 L2 // leave slice (4/24)
[] = U F2 D' B2 R2 U' B2 U D2 // +1/25

Optimal from DR.

This was the only "good" DR I found, but there was this really blocky DR that I wrote as a backup earlier on:

R B' D F // EO, 4c4e (4/4)
(B2 L2 U2 B2 R2 D B2 D2 L) // DR (didn't even check HTR case but it was 2c3 2e) (9/13)
(F2 B2 U' B2 U' B2 @ D U2) // just build blocks, ab2e2e (8/21)
@ = (B2 U2 R2 U2 B2 R2 U2 R2) // fin (8-3/26)

Optimal finish is +12/25 (so not any better):
nissy-# solve -t 24 -o R' U' F D B' D R' U' L2 F R B2 U2 R L2 U2 L B2 U F' R' U R' U' F    R B' D F (B2 L2 U2 B2 R2 D B2 D2 L)

R2 B F2 D' // EO (4/4)

# U2 F2 D2 # R2 F2 R2 B2 // leave slice (7/23)

# = M2 // -1/23

Optimal from DR.

The next best DR I'd found was an 11 to 2c4 but like, I was sick of doing 2c4 already.
(Do I really want to have a whole mean with 2c4 DRs? No thanks.)

U' R' U' L' F // EO, 4c4e (5/5)
R2 F2 U' D B2 U' R // DR 4b5 (7/12) (+15/27)

R2 B F2 D' // EO (4/4)
B // 4c4e (1/5)
L F2 R2 F2 R' D2 L2 F // DR 4b2 2e (8/13) (+12/25)
