Spent a lot of time on checking various phantom HTR after i undid something wrong. 10m+ down the drain and I barely touched the 10+3 from this EO because of it...

F2 D U2 F2 B2 R //DR 10+4 2c4e

Had this slice in 21:
B R' F' L' (B2 R2 F' B R2 F D) //11+2
B U2 L2 B2 R2 B D2 L2 U2 R2
This might just be the worst i've ever seen and i was unable to solve it within the 1h.
Slice is a +2, but best i found is +3 and i did it very late, so didn't manage to write it down in time

The 11+2 is 23 optimal but the other variant has a simple 22 i overloooked
The 10+4 is also 23 optimal, but only with via a unique 6q leave slice

Had another slice in 22 from this but somehow both 4q slices with a blockyfish are +1 optimal...
DR opt is a crazy 21 with both flipping and RLUD hackery.

Also had:
(R) D2 F2 L2 R' U R' D R L //epic DR that I found by:

(R' B' D2 F) //EO
(R L) D2 F2 L2 R' U R //12+2
R' L (R' L') // DR-fe hack
(F' D2 B) // further undoing stuff
L' R' D R L //fix 4fe for a 10 move DR, of course it's 5qt/
Might be the first time I use this during real attempt, not sure.

(L') U2 B R L' //EO
(D' R2 U2 R2 B' L2 B) //DR 12+2 4c2e, most variants ever

This is 21 optimal with the M(M) 0e trick & 5qt

I think this might be the craziest scramble i've ever done. Didn't manage to check all 4 move EOs, couldn't switch all 4 move RZPs, stopped writing 10 to DR very early into the attempt and only looked VERY briefly at DR that were promising.
Notes are so messy I'm not even sure how to aproach post-attempt analysis...
