DR is 22 optimal. Silly miss, but i was looking at (...) R D B2 R' B2 D variant and only realized about this very late into the attempt.

Other variant has a 21 but it's a tricky one as you have to U R2 S2 R2 U extend the DR.
Also looked at:

D2 B' U R2 D' B //10+3 2c2e, 22 opt

This DR has a simple 20 after R F' B => R U2 F' B extention. For some reason i checked R D2 F' B and went on.

(B U2 L) //EO
(B') D' B2 U F //DR 8+4 2c4e
(D' B2 D L2 B2 D B2 D') //HTR

DR is 20 optimal and easy to find. Not sure what went wrong

R F2 B2 D2 L F2 L //HTR

not even sure how to find optimal for this with NISSY, hopefully someone used it as final

D2 F' L2 U2 [B2 D2 F] //HTR

So much good stuff and only a 20 in the end.
Spent too much time on
(U2 R')
(D' B U2 B2 R2 B2 U) //9+4 infinity variants

There's a cool 19 after a 3 move setup to 7c6e 5-mover. 
Tried some similar stuff but didn't spot this one

One of the most epic EO->DR that I remember doing. 2 move RZP based on vibes -> fun 5 move trigger

The DR is a 4-cycle of edges and a bunch of 2-swaps, so normal and inverse are very similar. All the same HTRs work, and they are all H-perm from their "twin" on the other side of the scramble. Very wierd

DR is 20opt with a very simple 4q path, not sure why i didn't see it
I also looked at extentions VERY briefly and probably should've spent more time here, as there was an 18 to find

Wrote this last second. Was jumping between 4 different 12+2s, but none of them were good.

DR is 22 opt, but i spent too much time on:
(L) D2 R2 D' R
B' U' F2 D B //10+1, 23 opt

Somehow missed the most obvious 22 from:
F2 U' D' R 
D F2 U2 L2 U' D2 F //11+2
U F2 L2 U //HTR and triple slice in 15, somehow missed +7 from there

DR finishing was abysmal. Kept going back and forth between the 9+2 and two promising 10+3s and fumbled in the end.
