Had 2 22s to slice but both are +2 optimal, here you should do D2 F to HTR-4E and switch for 23 optimal

L F B' U // EO(4/4)
(F2 L R2 F' R) // DR, 2c3(5/9)
(* D2 F) B2 L2 F' D2 F // HTR(7/16)
U' D B2 U' D' // 2E2E(5/21)

* = B2 U2 B2 D2 F2 D2(6-3/24)

Good for scramble, bad for dr( Very easy 21 from this dr:
U2 F2 R2 F U2 B' L2 B // HTR(8-1/16)
R2 U2 R2 F2 * // 2E+slice(4/20)

* = F2 R2 U2 F2 R2 F2 U2 R2(8-7/21)

And solve slice in +0

I'm so sad I didn't find optimal, i tried inserting D2 into that htr but not U2😥

After analysis: 
Missed quite easy 21 off U2 L2 F and switch, tried D2 R2 B but didn't work, and it's the only way to get sub23 on this dr

L D2 F' B2 L // EO(5/5)

Just awful, the best scramble in terms of eo I've seen in a while

R U2 R // EO(3/3)
D' R2 U' F D2 F' // DR, 2c3(6/9)

WTF it this scramble, 22 feels like an awful solve

Thats my pb single!
Actually, first found this dr: (F U B' D' B L F' B2 D2 R' F2 R), which is 4a1 in 12, and decided to switch after jzp first, and found this dr and solution in like 20 min. After checking all other eos i came back to original dr, and it turns out that it could give the same solution
L2 B // HTR(2/14)
R2 D2 B2 D2 // M slice(4/18)
Which is literally the same solution, so it could've been 12+8 lol

U F' D2 L' D // EO(5/5)
B D2 B2 L2 B' R2 F' R // DR, 2c3(8/13)

After seeing solutions:
I had (R' D' L2 B) R D2 written on my paper, but somehow i missed 12+1 from it🤦‍♂️
