DR is 20opt with a very simple 4q path, not sure why i didn't see it

Somehow missed the most obvious 22 from:

Getting unique DR optimal on this variation hell is really cool, especially that it's a qt right after double slice section. 
EO opt is 20 from a DR in 14, but it keeps EO solved andalmost looks like some DR-breaking magic. 
Mallard finds a 20 from a 2+3 EO, as always.

DR is 21 opt, but I skill issued.

+1 on 4q is sad. 
Kept undoing stuff incorrectly and wasted so much time. 
DR is 24 optimal, but the fact that this is best I had is 

L (D' B2 R) //EO
(F2 B2 D' L2 U2 B) //DR 10+3 2c4e
(R2 D R2 [U' L2 U']) //HTR
(F2 L2 B2 L2 D2) //leave slice

DR optimal for this.
Spent some time on:
L (D' B2 R)
B2 D' L2 D2 B //9+3 and variants.
There is a 21 there but it's a tricky double slice even when looking at the right variant

Idk what i was doing. Was staring at HTR in 14 for so long an didn't find the 7 move finish still. 
Wrote some slice in 23 and inserted it last second, just so I don't DNF...
Spent some time on:
(R' F' D2 L) F L2 F2 R2 D B //10+2 but this got me nowhere

(R' D' F) L (D' R2 U' B2 R) //DR 9+2 -> instant 22 on normal

Found this with a single pass, while resolving he cube after the RZP looked bad.

DR opt is 21 and there are 22 with 2q.
Not sure where my thoughts were when I was finishing this DR.
Didn't have a lot of promising stuff otherwise, some DRs in 12 that looked good, but no sub23s there.

SO much stuff there and I missed everything good. 
Was about to quit for good when during analysis I saw 3rd missed 20, on (U) R2 B2 D L //JZP, that i grilled hard during the attempt, but it's abandon JZP and do U/D DR on U/D EO bs.
At least I got opitmal from all variants of the DR, despite huge JZP sequence, so thats good.

This DR is 21 optimal and super easy to find too, as it's just U *S2* R2 U extention of my HTR, but i forgot to check what it gives on other DR variants...
