This is a variation of the original DR, so I didn't have much time to find optimal on it, which was 22, that required 2 moves to qt and then switch, quite findable, but not in a short time.
The original DR was 23 optimal, but I don't think it's findable

I had a 2c4 in 10, but it was 3 moves to 2c3 on both sides, and for some reason reduction to 4b3 just didn't work, so I played with this dr for a while. Optimal from 2c3 in 12 was 25, It was just a 3 move reduction to 4b2 2e, but I did't check it cos it was my 2nd DR. 
Meanwhile 2c4 in 10 had a 23, quite a simple solution tbh, just 1 move to 4b3, then U B2 L2 U to 4a1 and on inverse it's 3 more moves to HTR in 9 and then just 4 moves to slice in +0.

I only had a single 4 move EO, I cheked all 6 move RZPs from my 25 EOs, and all I could find was 2c3 8e in 14, but then I decided to switch (B' U' D L), B2 U and got this 4b2 4e in 13.

This DR had a 25, and I actually had the HTR, but didn't think about doing a DS as [L2 D U' R2 D U'] U

Optimal and the only 24 from this DR.
Sadly I wasn't looking at 78 triggers, so I missed 18, but whatever

E' // +1/25

The only 24 from this DR was 3 moves to a 5 move trigger, I should've cheked, but optimal +1 isn't bad

R^ D2 B2 R (L' D2 B2 L D2 L^) // HTR (10/20)
(F2 L^2 B2 L2 B2 U2 B2) // LS (7/27)

I was pretty sure I had a 4b2 2e in 10, so I wasn't to focused on looking for more DRs, but apparently I misstraced the parity on 4b2, and also a DR that I wrote as a 2c4 in 10 was in reality a 4c4, I played with it but moved on to this 2c5 in 10, which wasn't very good. Unfortunately a 27 from a good eo set

B L2 B2 F D // DR, 4b2 2e (5/8)
(R2 D2 B2 D2 B D2 B2 U2 F') // HTR (9/17)
(R2 D2 F2 U2 R2 F2) // Finish (6/23)

Missed pretty findable 19 from this, also plenty 20 and 21 solutions that I missed, sad

B' L B', L' U // EO+RZP (5/5)
L R D2 U2 B2 R' U' // DR, 4a1 4e (7/12)

F2 L^2 U2 F2 R2 // LS (5/23)

M // +1

Barely cheked any EOs so I didn't have anything good besides this, also I was quite slow at checking HTRs here, though it's optimal from DR but if I actually checked if there're any variations I would've found a 23. 2nd solve in a row I lost 1 move because of simple solutions from variations I forgot exist.
I also missed R2 D (F2 U) eo, that gives an easy 9 move DR, though it's 2c3 6e, but with a 2 move setup to a trigger it gives a 2 move finish, so it's a missed 20 I guess

(L) U2 R', U' F' // EO+RZP (5/5)

D2 L2 F2 U' L2 B2 U // HTR (7/18)
R2 $ B2 R2 // 2e (3/21)

$ = R2 U2 R2 D2 L2 D2 // +3

this had at least 4 variations, I only partially checked 2 of them. apparently 3 of them had 23 optimals and 1 had 22 optimal (I didn't check that one).
I also tried to insert M slice at the end to cancel the R2 L', but I didn't find anything

Absolute Cinema of a solve!
I had a 4b2 02 in 12, which is good enough for me to solve tbh, then I found 2c4 in 9, where I was ready to stop looking for DRs, but, even though I was a bit behind my time, I decided to check 1 more niss RZP(DR-4e2c in 4) and got this 2c3 2e in 10 from it(with a variation). On normal it's literally a 5 move trigger from being solved, which gives you this LS in 21 which is +0. I played with many other triggers as well as with the DR variant, but I didn't find anything better. At the end I was trying to somehow reinsert the U2 D2 F2 U2 D2, which can be swapped for B2 making it a non DR Slice in 17, but I wasn't able to find anything better. 
Sad that I didn't have those extra few minets on my last solve, cos I would've had a 21 21 at this point

D2 L D, (B') // RZP (4/4)
B2 D2 R2 D2 R2 L' [F // DR, 2c4 (7/11)
(F2 L' B2 L^' B2 D2 L^' U2 L) // HTR (9/20)
(B2 D2 [L^2) // DS (3/23)

[] = B U2 F B' // +2/25

The cleanest DS insertion I've ewer had, pretty good solve, though If I had a little bit more time I would've tried to switch after (F2 L) which gives double square trigger for 2c3, and one of the variations is just 2 more moves to solved(L2 R2 away)
D2 L D, (B') // RZP (4/4)
B2 D2 R2 D2 R2 L' F' // DR, 2c4 (7/11)
(F2 L) L' U2 L B2 D2 R // HTR (8/19)
 F2 U2 // LS (2/21)

And the funniest thing is that when I inserted 2 random slice moves to fix the L2 R2 away-ness (idk how to insert LS without fixing that), the cube was just solved.
D2 L D B2 D2 R2 D2 R2 L' F' R' F2 L U2 B2 L B2 D2 L' F2 B 
This 21 can also be found without switching as a 
(F2 L), then 2 moves to 6 move 2c3 trigger and the cube is literally solved after that LOL

From that DR I had double slice in 23, which had a 26 solution, but I didn't have enough time to find it. 
there was a 25 with 2 move setup to 5 move 2c3, that I missed. Optimal from DR was 24, but it was 6qt, so not findable. 
Not a lot of EOs, only 1 DR in sub13, but all of them were 4-5qt

B2 R2 // LS (2/25)

I had LS in +12 but didn't find any insertions in +1, so I tried this one(LS in +13), which is almost exactly the same as my LS in +12 but solved with a switch and a slightly different solution which actually gave me a +0 on my first check.
2 move eo is stupid but I didn't find anything good besides this and 2c4 in 11

wtf?
after seeing an 8/8/10 I was ready for the worst. wrote down 12 5 movers and 28 6 movers. 7th eo(2nd RZP) I got 2c4 in 10, already crazy, so I stopped looking for DRs after finishing the 5 movers. at 25m I started tackling the DR, I was execting nothing good because it required 2 half turns to 2c3 on both sides, but my 1st solution(2c3) gave me a 3 move finish after a 10+10 to htr at 27th minute. I'm not checking the solutions through 4c3, cos I'm lazy and shocked
