I also misrecognised the case after switching B R' B2 L, B ... and it leads to an easy 20 of course.

This DR has 22 opt variant and it's the best possible result here.
Other than that there's just some other 22s from silly 4->5 extentions and 23s elsewere.
With 2x 3movers and >20 4movers, I was expecting something else, but that doesn't excuse missing DR opt by 3 on a stand-out DR.R' U' F L' D2 F R2 B' F2 L2 B2 F' U' L2 F2 L2 F' R D R B' D2 R' U' F

I missed a 2+2 and the only sub-22 that doesn't use it is of a 4->5 on F/B normal, so a casino with 64 possible extentions... Plenty of 22s though, but i was just too slow and not precise enough.

I don't remember seeing the shape of the inverse, so maybe i missscrambled...(?) All other 19s and 20s look too tough to find on a sprint scramble like this, oh well :\
