Optimal after DR.
This was my only DR under 11 moves.
I wrote down and checked 56 EOs this attempt.

(B' U2 F' U F) // EO
(L D' R D' R) // 2c4 (10)
(B2 U) D' L2 B2 D L2 D // HTR
L2 F2 D2 F2 // Slice (22), +1/23

(D) U2 B D // EO
R (L2 F' L F' R) // 4b2 (10)
(U2 F' U2 F' U2 F R2 L2 B) // HTR
(R2 F2 R2 U2) // Slice (23), +0/23

(L U' B L') // EO
(R2 U' F2 U D2 B') // 2c3 (10)
D (L2 U2 B2 U' B2 U') // HTR
B2 U2 L2 F2 L2 // Slice (22), +0/22

18, 25, DNF = no
best mo3 i got with the 18 was 21.33 with two 23s before it

Really terrible solve. Basically a DNF.

R2 D' (R B U) // EO
(L) L2 F' L' F' L // 2c3 (11)
(U2 R2 F U2 F U2 B') // HTR
(L2 B2 R2 F2 U2 D2) // Slice (24), +1/25

I had this DR, but didn't find anything from it. Optimal gives 22.
D (R2 B U D2 F2 L') (F' U2 B/B' R2 F) // 10 to 2c4

No doubt the easiest sub-20 ever. Literally the first EO I checked. I ended the attempt after 20 minutes.

D' R L' B // EO
U R' B2 U B2 D // 4a1 (10)
R' L' ^ U2 L' // 3e in 14
^R U2 B2 D2 L D2 B2 U2 // 8-4 = 18

Optimal finish. Scramble optimal is 17 but unfindable. Tied PB lmao.

D' F' U2 L' // EO
F D2 F2 U B' U2 B // 4b2 (11)
D L2 F2 U' R2 U' F2 U // HTR
R2 B2 U2 R2 // Slice (23), +0/23
Optimal after DR.

I also had this:
(B2 D R' U' B' R) F2 B' R' F R // 4b2 (11)
U2 D2 F' L2 D2 F' D2 R2 B2 U2 D2 // Slice (22), but +2 unfortunately.

My third 11 to 4b2 was this: D' F' U2 L' F (U2 D' B D2 B). Optimal across all of my DRs was 23 moves.

R B' U' D' // EO
B2 L2 R B R' // 4c3 (9)
B D2 B' L2 B2 R2 U2 B // HTR
L2 D2 L2 F2 // Slice (21), +0/21

B' R2 D2 R' F // EO
(R') U' R2 U' F2 R // 4b2 (11)
(U2 L2 F2 U' L2 B2 U) // HTR

F R' D' F' B // EO
L' R2 D' F2 U2 L // 2c3 (11)
(F2 D' B2 D' B2 U) // HTR
