9 move DR has an only sub 22 findable, missed it (not easy to me)
10 move DR is 22 opt with 5qt 

Missed the +6 to DR for 11 0c0 apparently

What a bait scramble 

Optimal from my DR's
Edit I found Joseph's DR, miscounted it as 4b2 4e in 12 so forgot about it as it was very early

Are you kidding me ???

Never came back
DR is 20 opt

Had other 21's and not the one I actually wanted to submit until I turned on my devil friend Mallard

Idk I keep wasting my time on first EO's I check, looking for 5cxe 3c4e and stuff and tracing pairs but never works, and checked very few EO's.
So I missed a 20

DR is 19 opt with unfindable 4qt path and especially if you already have 20.

Close on time, had 22 backup from normal on same var.
Spent a lot of time on :
(F' U B2 D)
L//JZP
(F2 B2 L' U2 R)//4a1 4e (10). You can do both variants of the EO and of the trigger but nothing is good with 1qt, 21 opt

A lot of 21 opt DR's so good finding DR's step, but finish was too stressful

Pfff

(L2 B2 D')//EO(3)
F R2 B2 R L' U2 R F//4b2 4e (11) billion variation but this one has 4 move HTR's
R' U2 F2 R//HTR(15)
D2 B2$ R2$ D2 R2//S slice(20), insertion of S2's $ to +2 backup

Had DR for 19, not the correct variant and forgot about it.
Found 22 on other variant but sucks that only one from all 11 move DR's is lot better than the others

Imagine writing 50+ EO's and the first one checked is..

21 21 19 is nice, finally coming back to pratice 
Cool DR also :
L R2 B//EO(3)
U' R2 U' D L U D'//4c3 (10), not good

R2 B//EO(2)
(F2 R') U *B2 D' B2 R'//0c0 6e (9)
*L2//now it's 4e(10)

(U') B2 L2 F2 D//HTR(15)
R2 D2 F2 L2 U2 F2//Slice(21) +0

0c0 in 9 did not work, I did try some extensions.
Also did find the DR's in 10 that give 20 linear HTR's were bad and too many of them to do and not enough time

First
(F R L' B')//EO(4)
L' B2 U' B2 U B'//10 4b2 4e
F2 U (L2 B2 D')//HTR(15)
(B2 R2 F2 R2)//Slice(19)

+3 grrr

F2 R2 U B' R2 F'//10 2c3 double side variation
U' (B2 U L2 U')//HTR(15)
(L2 B2 L2 B2 D2 R2)//Solved(21)

Spent +15min on 2c3 after having 22, a lot of other mid DR's but one of the only 21 on scram so I'm happy

U' D2 L B R'//EO(5)
U2 L2 U B' D//4b2(10)
(U2 F' D2 F' L2 F' U2 L2 F)//HTR(19)
(U2 F2 R2 U2)//Slice(23), +0

Spent 20+ min on this single DR, was my best

(L) U' F' R L//Magic EO, I did not try F2 and B2 before U D So missed the I guess kind of findable maybe 21

DNF,did not find anything off 4 movers and bad time managment, did not write enough 5 move extensions

L' D2 F' U
(R2 B2 L B L)//9 2c3 6e Already have better DR's so just check 1-2 short linear HTR's ?
(F' R2 L2 D2 F' U2 F)//HTR(16)
(R2 D2 B2 L2 R2 U2)//Slice(6-1/21) ok
+1 for 22, found around 25 min

Then finished checking my EO's and spent 25 min on : 
R2 D' F', D (R2 U' B2 U)//8 2c4(2 variants);
(F R F D R F L2 F' L)//9 2c3 4e
(F R F D F2 L2 F R F L)// 10 4a1 4e
(F R F D B2 R2 F R F L)// 10 4a1 2e

Turns out my only hope for 21 was the JZP extension of 8 2c4 which I really dislike doing and the resulting DR in average is worse than all of these, but ofc both variants have findable 21 that a lot of people will get I think...
