(L2 D R B) - (R L, U' D2 L U L) // 11+idk
and also 6e vars of the DR from my solution

idk how i missed U' R' F D' - R and switch for a 22, sad

D' R' F2 L
(F' B) D B2 U' B' D' F // DR, 4b2 2e (12)
{(U2 L2 D' F2 U')}
[(B2)] // 2e+E (18)

[...] - (F' R2 B2 L2 F2 L2 F) // slice (24-2)
{...} - D' U2 L2 D B2 U D (+2)

very unfocused, switched (F B) here but forgot about (B) for D R' F2 L

wanted to be fancy too much this attempt, also i got distracted by the fact that there were both R L (R' D2 L) and (R L) R U2 L EOs lol

F' (R2 B2 U B')
L, B2 R2 U R' // DR, 4a1 4e (10)
(F2 U)
R L F2 R' L' U2 F2 R2 B2 R2 L2 // finish (23-2)

found because i was switching F (R2 B2 U B) (D) // 44 2p

still missed a 20 from the S2 HTR ext, i took a look at it but somehow underestimated the other axis (the case was pretty similar to the 12 move HTR)

if not for that i would've had to squeeze something out of these 10+4 2c vars:
F R' D L' F - R' L U F2 U
          F' - R L' U' R2 U
there is also a 9+5 after switch here, EDIT: ok i see there is a fairly easy 22 from that, cool

B' L' D F2 U'
(F' D2 L') // DR, 2c3 2e (8)
([B' L2 D2 B' D2 B')
(L2 B2]) // slice (16) ok

[...] - F' D2 R2 F B2 D2 B F2 R2 F2 (+2)

it took me embarrassingly long to try this HTR after i found the DR but either way a nice start to the league xd

B' (L D' R2 B')
(R2 U2 F2 L2 U2 R) // one of the million vars of 11+3 2c4e (11)
U (D' F2 L2 D')

i spent so much time here, i'm sad

had a lot of DRs but nothing wanted to get solved:
B' L (R2 B' L) - (B2 U D2 F U2 F) // 11+3 4c
B L' F2 U' R - L2 F2 L2 B F2 D // 11+2b 4e

(L' D F' B' U') - (F L2 B2 U2 F R) // 11+2b 4e

ok WTF i didn't have the 3 move EO, idk

(F2 D L2 U' L') // DR, 2c3 4e (9)
(D' B2 U L2 U)

only found 19 to slice on the 7+3

bad solve

other:

(L U F2 B' D) is DR-4c2e, marked that but forgot to switch

the legendary 8c8e JZP from mallard for a 19:

(B) R' L' D F - L F2 R' U' F2 U // 11+4 2c
(L U' B R) - U (U2 F2 L2 D) // 9+5 & a lot of bad DRs in 11 (still somehow missed the only good DR in 11 here)

(F') F' U' B'
(U' R, D2 R' U' R') // DR, 4b2 4e (10)
(B2 U) R2 B2 U2 F2 U
R2 B2 R2 F2 // slice (21), +1

this DR also has a 4q 21 to slice that i didn't find but it's +2 lmao

there is a 7 move DR from F B (B' L' F) for a 20 but i only traced after (F B) and not F B sadly

other than that i rather struggled this attempt:
U B R F' - U, D2 L D R D // 10+4 2c
           U (F2 L' R' D' R' D) // 11+bad
           R (L2 D R2 D R) // 10+5, edit: lol this is 10+3 4c, misrecognized during the solve
B' U F L2 D - U2 B' R2 B' F2 R // 11+bad
(F' U2 R) - F' U B R2 F' L2 F // 10+4 4c

(L U' D R)
(B D' R2 U L2 U) // 10+5 but it's only a blockcomm left ???
(B' U2 [F' L2 F L2 F' L2 F]) // slice (19)

[...] - B' U2 F U2 B' R2 F' B2 (+1) ok

other:
(F' L U2 R' B') - (D2 B2 U B2 D R) // 11+idk
(F) U L2 D' F - (L', D' R2 U' D2 R) // 11+3 4c
(L U' D R) - (U, F2 U2 B' D' R2 U) // 11+idk
(L2 U L' B' D) - U2 F' U2 B R // 10+4 2c
(F L' U' D R) - R2 U' D B // 9+3 2c4e, 21 opt

B' (L2 F)
(L2 D') F2 U' R2 L2 D' // DR, 4c3 (10)
(R) R2 F2 R D2 F2 R
D2 F2 L2 D2 F2 // slice (22), +1

i had so many mid 10 move DRs with vars from this EO and not a single 22 to slice wanted to be +0 (i had 4 different ones)

not really sure how i missed this 8 move DR for a 20:
B' (L2 F')             // eofb               (3/3)
(R)                    // rzpud-eofb         (1/4)
U2 L2 U' R             // drud-eofb [2c3 6e] (4/8)

i really don't know, i was checking every +1 and don't have the rzp written down, probably misrecognized

EDIT: looking at Xiwen's solution i realised i missed a 20 from that DR because i forgot about this variation when checking reductions to 1qt, i only checked the ones beginning with R/R' F2 B2

(F' L B U' F) // EO 44 4p
U2 R' L F2 U // DR, 4c3 (10)
(L) R' U2 R
F2 U' D B2 U' D' // slice (20), +1

also another 21 from the same variation:
(F2 B2 R) U2 B2 D2 L F2 L // HTR (19-2)
U2 F2 L2 B2 // finish (21)

other:
(B D L F')
(L U, R' U F2 B2 D) // 11+2b 2e
(F2 D2 L F2 L')
(D2 B2 R2 U2 D2 F2 L2) // 23 backup

B U' L2 D
L, U2 D2 F D2 F' R // 11+4 2c

kind of lucky because i wasn't checking the 5 move extensions of 4 opt EO cases systematically, just some of them at random

U2 [R U2 R
B] (U' R2 L2 U' B') // DR, 4a1 4e (10)

[...] - R' L2 D2 ^ R F // extend (+1)
{(F2 L2 B2 R2 U) // HTR (16)
(R2)} // 2e2e+slice (17)

^ D2 R2 D2 R L B2 R' L' (8-5) // slice (20)
{...} - R2 D' R2 F2 U' D L2 F2 (+2)

the original DR has 4 HTRs in 15 on both sides and there is a fairly normal 22 there as well (and also 21 from a HTR in 14 i had but forgot it cancels 2 so thought it was in 16 lol) but i didn't notice that at first & at least this was more fun

let's also maybe not talk about the missed 20 from the same RZP but everything on normal (4th league solve in a row where i miss +6 to DR)

other:
D (D2 F' R2 U) // EO+JZP with DRs in 11 but didn't look at them

U' R U R
D', U2 L2 U2 B U // 10+4 4c

B L' F U2 R
(U2 F' B' U2 B D') // DR, 2c3 4e (11)
(F U2 F D2 L2 B)
(U2 D2 R2 D2) // slice (21), +2

also had slice in 22 from this DR but cooked as well

also there is this from my EO:
(L2 B2 R2 D2 F' U) // DR (11+3 2c6e)
R' B2 R2 B U2 R2 F' R2 D2 B U' (11) // (20)
which marks 3x +6 to DR missed in this mean nice

disappointing attempt, i feel like i spent too much time on various 5 movers (given there were some 4 movers and also the 2 & 3 mover) and it didn't turn out very well

other:
B' L (F' D' L)
(B', U D F D' F) // 11+4 4c

quickly checked in online mallard before the actual analysis and it shows this DR for a 19:
R (R D R')            // eolr               (4/4)
U                     // rzpfb-eolr         (1/5)
F L2 D2 U' B U        // drfb-eolr [4a1 2e] (6/11)
i had the rzp but didn't do +6 to DR (2nd solve in a row where i miss a +6 to DR for what seems to be human optimal)

other (only what i worked on):
(U L2 U' R)
(B2 U F2 R2 U' B) // 10+2b 4e

(U') U B2 R2 L2 D'
F2 D2 B2 R2 L2 // slice in 21 but after a very quick look i don't think it's +0, otherwise would've submitted it for fun

i missed this DR, i think a lot of people will find it:

other:
F' L (D B' L)

i should've found this:

L2 F' R2 F (F B)  // htr-drfb   (6/17)
(R2 U2 F2 R2 D2)  // fin        (5/22)
but missed this +6 to DR, need to work on my 7c8e lol

why did everything have to be so symmetrical and bad here

A very blocky variation with premade sq/sq but best i found was 22 to slice +1

missed slice in 5 (only did a 2e+slice skeleton there for some reason) for a 22 and also slice in 21+1 lol
