Best optimal from every DRs I found was 24. Uffda

I found a few 13DRs that were decent qt but nothing good. 
Mostly worked on the 11 DR 4b2 6e and kept getting pretty frustrated even after checking 4qt.

I didn't find a single DR with less than 4qt so I just had to go with the only sub-11 DR I had. Optimal was 23 but not sure the best way to find it.

F2 R' U2 F' // R, (F2 U2 L' D2 L) // 10 DR 4b2 (22 optimal, niss traced the DR and forgot to go back and look at it)

Tried some 3qt options but don't think I would have found the 22 with it.

Honestly not a good attempt for me. Didn't find any great DRs. Glad to find a decent finish on one of my DRs.
Best DRs I found were:
R (L U' L') // (D' L2 B2 U F' U' B) // 11 DR 4b3 (22 optimal only from 5qt although I found a 19 to 3C for a 25 on this)
(L) R D F R // B D', R2 U L2 U // 11 DR 4b5 (24 optimal)
(L) R D F R // B, (D' B2 D' R2 U D2 F) // 13 DR 4b2 (pretty weird 24 optimal

B2 D R' // EO
B, U L2 B D2 B' D2 B // 11 DR 4b2 4e
L2 B2 U' L2 D2 F2 U2 F2 U' // 20

This is how I found it. First did L2 B2 U' to do the first quarter turn of the 4b2 4e and saw the finish after.
Luckily I did the correct DR variation the first time and didn't have to find the finish from a slice.
Optimal after the first two moves!

Other nice DRs I found:
B' D2 L' B // D L D R // 8 DR 4a2 (also found the 10 DR 4b2 4e and 9 DR to 4a2)
(U2 F2 U2 B') // (F2 R B2 L' D) // 9 DR 2c5 (23 optimal)

Other decent DRs I found:

Rough scramble
Optimal on my DR is 23 by doing:
[U2] R2 L2 F' L2 D2 L2 B' // D2 R2 F2 [R2] 

Only other DR where optimal was sub-25:
U (B2 F D) // (F2 L, F2 R' F' R) // 10 DR 4b4 (23 optimal)

(R) D F U L // EO
F R2 B D' R2 D' // 11 DR 4a1 4e

[] - B' L2 F B' // +1

Edit: Dang didn't even consider the variation of F L2 F D' F2 D after EO. Good learning moment.

Only other decent DR I had was:
B' R (B' L) // (F) U' F U B // 9 DR 4b5 (22 optimal)

L (B2 R D2 L) // EO
(D B2 L2 D2 L2 D2 F') // 12 DR 2c3 2e
(L2 U' & B2 D L2 D) // 18 HTR
(B2 R2) // 20 to 2E2E

& - U2 F2 U2 B2 D2 B2 // 6-4

I first tried solving the 2E out of the slice that left 22 to slice and found a 23. Then went back and found the direct 2E2E insertion lol.

I first found this continuing on inverse after HTR:
(D2 F2 L2 U' D R2 U D' L2 D2) // 24
Then I tried switching after HTR and see if I could find the cancellation into the last move of the DR.
