F B (R' U2 F) // EO
L2 U2 F2 L2 U' L // DR 1q in 11

And now for the degenerate replacement fun

F B L2 U2 F2 L2 U' L // Stuff on normal
(R L2 D2 B') // EO variation
(F2 U2 L2 D') // HTR in 16

...

(R L2 D2 B' F2 U2 L2 D') F B L2 // Stuff on inverse and first 3 moves on normal
R2 U D R2 F2 D L // HTR in 18???
F2 U2 F2 B2 // Solved in 22 lmfao

I nearly found all 17 5 move EO's on this scramble, somehow the only ones I missed were the ones starting with R on inverse then switching xD

Cool solution 

U B R D2 B // EO
F2 U2 F2 R D // DR
(D2 F2 [L' U2 L]) // HTR
[] = (L R2 D2 L R2) // +2 that sets up nice wrong slice case
(U D' R2 U D') // Solved in 22-1=21

Found this DR on the 80th EO I checked out of 85 total checked EO's... Worst 4 badx2 I've seen in a while lol

20 and even 19 seem somewhat possible using variations of the DR, but they all require 4qt despite being good 4b2 on both sides of the scramble

Had 3 total 21 to slice from this DR set (2 from this DR and one from D L2 D2 R' on normal), this was the only one that +0'd :P

had a 23 from (D' L B U' F) L R B but couldn't write correctly under the hour :(

also had B R2 B' U (D' L2 U2 B' R) which i found nothing from

(L2 D R L) // EO
[U'] (F' D2 B' D) // DR
(B^' R2 F U2 R2 F L2 F^') // HTR/S+E

^ - w // E

[] = D' F2 D U' R2 // Solved 

EDIT; I stopped my attempt 20 mins early & didn't bother finding Enrico's 20 oops :skull:

R' B2 F' R' // EO
U (L2 F B U2 B' D) // DR
R2 L2 B R2 U2 B // HTR
L2 D U' L2 F2 U' D // Solved 

Didn't find many good DR's on this tbh, happy with the lucky finish on DR in 11

B' D' // EO
L (R L2 D2 B' L2 B' R) // DR
(F L2 F2 R2 F' D2 F) // HTR
(R2 D2 R2 D2) // S in 21, solved in 22

The 8+5 DR that my DR is derived from gets 21 optimal & it seems somewhat findable, but I had better things to check on this scramble...
