DRs:
(R' U F), L, (U2 D F2 U F2 R) // 10 4b2 4e
(R B L' U, R' U2 L F' U2 B) // 10 4c3
(R' U F), L, (U' D2 F2 D' F2 R) // 10 bad
(L R' B U, B' U2 F2 L' U2 F2 R) // 11 4b2 2e
F2 D2 F' D, B' R F, L2 D2 R B // 11 4b2 4e
(R' U F), L', R2 F2 U D L2 D R // 11 4c3

(U2 R2 U' F', R L' F2 L R2 U2 R U) // 12 4a2 4e

mallard gives a 19 on (U) 4 move EO, but you have to switch which is a bit unreasonable given how many 4 move EOs are on this scramble

R' D2 R2 F L // EO (5)
U R2 D B D F // DR 4b2 2e (11)
(B2 U') F' B' U2 F B' D' // HTR (17)
R2 D2 B2 L2 B2 // leave slice (22)
didn't solve slice

R' D2 R2 F L, U' D2 L2 D F D B // ext DR (12)
(F2 D B2 R2 L2 D' L2) // leave S+E slice (19)
idek

edit: meant to check the (U) B' L2 U family of EOs but forgot bc i didn't write them out fully

U D (F' R' U) // EO (5)
F2 R', B D2 B' L' // DR 2c3 2e (11)
B' L2 U2 B' D2 L2 F // HTR (18)
L2 // leave S+E slices (19)
+1, +3 slices (23)

wtf

lol i had chris/walker's DR for a 22 but missed the finish 

R2 {D (F' L2 U) // EO (5)
(B L2 B' L2 B L' F' R) // DR 4b2 2e (13)
([B' U2 B) // HTR (16)
(R2] {D2 R2 B2) // leave S+E slices (20)
{} = R2 U R2 U D' L2 U2 // +2 slice (22)
[] = F B' D2 F' U2 B // +2 slice (24)

lol wtf is this

(U) R F' B' D // EO (5)
L D2 B2 U2 R2 F // DR 0c0 2e (11)
U2 L U2 R B2 U2 B2 R' // HTR, leave M+S slice (19)
+7 slices (26)

oops

U (F2 D2 B D) // EO (5)
R' B' R B' // DR 4b2 4e (9)
L' D2 R B2 L U2 L' // HTR (16)
F2 D2 R2 F2 R2 // leave E slice (21)
+2 slice (23)

lol this is DR opt

funny DR:
(B) U D B, (D' U2 R, D L U' L) // 11 2c3 4e

L D B U F // EO (5)
(D2 R B2 D' B2 D) // DR 4b2 2e (11)
R2 U2 D2 F2 L F2 L' // HTR (18)
(D' B2 D B2) // mini DR flip (14)
B2 D F2 U2 B2 U' L2 U D' // finish (23)

other DR:
(R' L) F' B L, (B' U' F') // 8 4a2 4e
somehow thought this DR was 5qt, turns out it is 18 opt 🥶🥶🥶

also i found that DR at 9 min xd

(R2 U' L' B') // EO (4)
U2 R', (D2 F2 U2 L) // DR 4c3 (10)
U2 R2 U L2 U' R2 U2 F2 D' // HTR (19)
B2 R2 U2 B2 // finish (23)

variation hell, found from (R2 U' L B', R) -> U2 R -> (R' D2 F2 U2 L)

L' D U2 B R' // EO (5)
B R2 L2 {B' D} // DR 4b2 4e (10)
(R2 L2 [F L2 D2 B) // HTR (16)
(D2 B2]) // leave S+E slice (18)
{} = B D U' L2 U // +3 slice (21)
[] = F' B' R2 B' R2 D2 B' // +1 S slice (22)

somehow this was the best optimal of the DRs i had

other DRs:
(B R) D' L, (B, D B U2 B) // 9 2c3 4e
L' D B U2 R', B R2 L2 B' D // 10 4b2 4e
(R U2 B), B2 L', U2 B2 L' D' L // 10 2c3 6e (forgot to check 🥶)
U2 B2 R' D F, D' R2 U L D' L // 11 2c3 4e
U2 B2 R' D F, (F2 D2 U' R' D R) // 11 2c4
L' D U2 B R, (R2 B F' R2 U2 B U) // 12 4a1 4e

also there is an 18 on an EO i wrote down but didnt check lol:
(F B2 L2 B' U) // EO (5)
B2 R F' // DR 4b2 4e (8)
(D2 F2 D2 R' U2 F2 R') // HTR (15)
(D2 L2 B2) // finish (18)

R F' (B' U' B) // EO (5)
D' L2 U' B2 R' // DR 2c3 4e (10)
L2 D' (F2 U' F2 U) // HTR (16)
(B2 L2 U2 F2 B2) // leave slice (21)
+1 slice (22)

bruh missed 21 that was a 2 move setup to 2c3 4e HTR trigger smh:
(...B') ... R // DR (10)
B2 L2 U R2 F2 U' L2 U' // HTR (18)
L2 F2 U2 // finish (21)

also missed a pretty findable 19 from mallard, idk how i missed that 2+2 EO:
L D (L U') // EO (4)
(B, L U2 F' L2 F') // DR 2c3 6e (10)
F2 R (R' B2 R') // HTR (15)
(L2 B2 U2 D2) // finish w/ no +0 slice (19)

L' B2 L' // EO (3)
(U D), B F' U B U // DR 0c0 2e (10)
R2 F' R2 U2 R2 F // HTR (16)
R2 B2 D U' B2 U' D // finish (23-3/20)

wow this EO has an 18 ffs, i am so mad

other DRs:
R' U2 R', U2 B F' D B U // 9 4b2 2e, variation is HTR in 12
F (U D B, F2 D' B2 R D R) // 10 4a1 4e
R' U2 R', (U D), F B' U B U // 10 0c0 2e
of course all of these DRs looked very promising from multiple variations

L2 B R' // EO (3)
D' U2 R2 U D' R2 B // DR 2c3 4e (10)
(F2 D L2 D R2 D') // HTR (16)
(L2 B2 L2 F2) // leave slice (20)
+0 slice (20)

lol, very scary scramble

(R U' L) // EO (3)
U F, (D' R2 D {U2 F') // DR 4c3 (10)
B2 U F2 U^ B2 L2 D2 L2 D^ // HTR (19)
{B2 // leave E+S (20)
{} = (B F' L2 B) // +1 (21)
^ = w // +0 (21)

evan impression

other DR:
(R U' L), L2 U2 D2 B' U // 8 4a2 2e, also 21 opt

L D2 R' // EO (3)
F' L2 D2 B' D2 B // DR 4b2 4e (9)
D (B2 U2 F2 L2 U') // HTR (15)
(R2 F2 R2 U2 F2 B2 R2) // finish (22)

this might actually be my least favorite variation hell so far

edit: i forgot to whack the variations with reductions to 2c3 but i am not sure if i had enough time regardless

R F2 D B, R, B2 D' L2 D' L // 10 2c3 2e, 23 opt
R F2 D B', R, U' F2 L2 U' R // 10 2c3 2e, 22 opt w/ 5qt
(U B2 D B', L B2 L R' F2 L U) // 11 4a2 4e, 23 opt
R' B2 U L, U' D, F L2 U2 B U // 11 4b2 4e, 24 opt w/ 4qt

i missed R D B, R' D, (U2 L' U) // 8 4c3, 21 opt

what a miserable experience

(F' B' D L') // EO (4)
(R2 F' R2 F' U) // DR 2c3 4e (9)
R2 B R2 B' D2 R2 L2 F // HTR (17)
L2 U2 B2 R2 L2 // leave slice (22)
+0 slice (22)

i missed D F2 R', B D', F2 B' U // 8 2c4, 21 opt

i had F' D R, U2 F B', D' L2 U F // 10 4b2 4e, 22 opt

i originally undid moves slightly wrong, and thought that the above DR gave me 9 4b2 2e. this caused me to be quite lax during this attempt. i was also quite distracted (cope) during the attempt, which is unfortunate for a sprint scramble.

edit: i definitely switched fanti's EO but missed +5 to DR, i didn't know you could solve that 3 columns case so efficiently

(F U' R) // EO (3)
(U2 B' U2 F B L2 F2 B D) // DR 4a1 4e (12)
F2 D2 B // HTR (15)
switching back to inverse, we can make a shorter DR:
{F2 D2 B}, (F U' R, U2 F L2 B) // DR 4a1 4e (10)
{} = D' B2 U2 B // DR 0c0 2e (11)
U F2 R2 F2 U // HTR (16)
U' D F2 B2 U2 F2 U D // finish (24-2/22)

unfortunately there is a 21 on this HTR 🥶: D R2 B2 R2 U' B2 U D R2 L2

this was the last of all the variations i checked so whatever lol

F L' U D B // EO (5)
U' R2 F2 U' D L' // DR 2c3 4e (11)
D' F2 D' R2 B2 D' // HTR (17)
B2 R2 B2 // leave slice (20)
+2 slice (22)

lazy attempt, probably should've looked at the 3 move EO (and extensions) more

R (L U D' L) // EO (5)
U', (R2 F2 D B2 D) // DR 2c3 6e (11)
F2 U2 D2 F' (F' U2 F) // extended HTR (18)
U2 B2 D2 R2 D2 // finish (23)

missed (L D) R L' U, (U2 F' D2 L) // 9 2c4 (22 opt)

mallard uses 3c4e to find (F' B2 U' R B), R D' F2 B2 L // 10 4b2 2e (21 opt), i wonder who will find this DR

L2 B2 L' // EO (3)
(D B', L2 D {F' L2 F) // DR 2c4 (10)
D' L2 D F2 U' B2 U' // HTR (17)
D2 {R2 // leave 2e+M (19)
{} = B F' U2 F D2 F2 D2 B' // +4 (23)

variation hell on a bait scramble

F U2 R' F // EO (4)
(U2 B2 L2 R' U') // DR 4b2 4e (9)
B2 R2 D2 R (D2 R) // HTR (15)
(F2 D2 L2 B2 D2 B2 D2 L2) // safety finish (23)

somehow missed a 20 on this DR:
... F', (... U) // DR (9)
(F2 B2 L) R2 U2 L' // HTR (15)
U2 B2 R2 F2 U2 // miss easy +5 finish (20)

if that wasn't bad enough, i also missed the 7 to 2c4 that gives a 19 🥶

U B2 L' U // EO (4)
D2 F2 L2 F U2 B L' // DR 4b2 2e (11)
(U2 R2 B U2 B') // HTR (16)
(U2 R2 U2 D2 B2) // finish (21)

dumb

(B D2 F) // EO (3)
(D' L'), F2 U2 D2 R' D L // extended DR 4b2 2e (11)
R2 U' (B2 L2 D) // HTR (16)
(R2 F2 B2 U2 R2) // finish (21)

my only other short DR was D (U2 R' F2 U, L' F2 B R) // 9 4b5

R' D B' // EO (3)
(L), F2 U' D B2 U' L // DR 2c3 2e (10)
D R2 U' R2 F2 U' // HTR (16)
F2 L2 B2 // leave slice (19)
+2 slice (21)

D2 F (D' L' F') // EO (5)
(U' B2 D2 R' U' L) // DR 4a2 4e (11)
B2 L2 U L2 U2 B2 U' // HTR (18)
F2 D2 R' L D2 R' L' // finish (25-1/24)

there is a 20 on U' L U B' D', guess i need to work on finding all variations of U' B L U D :/

F2 R' U2 F // EO (4)
L D' B2 D' L D' // DR 4b2 2e (10)
(L2 F2 R B2 R2 U2 D2 L) // HTR (18)
(B2 L2 U2 F2) // leave slice (22)
+1 slice (23)

why

(F2 U), L' F R, B' R F2 B2 L // 10 4b2 4e, 22 opt
F2 R' U2 F, L D2 L D // 8 4c4, 23 opt (+15 🥶)
F2 R' U2 F, D2 L D2 L D // 9 2c4, 23 opt
F2 R' U2 F', R, (F2 U2 L' D2 L) // 11 4b2 4e, 23 opt

(R' U2 B D' L') // EO (5)
(R2 F B2 L2 D') // extended DR 2c3 4e (10)
B (L2 B' D2 B') // HTR (15)
(L2 D2 R2 B2 D2) // leave slice (20)
+1 slice (21)

found this pretty early and felt like there was a 20 on this DR but there wasnt. there is a way to get 21 without extending the DR too:

L2 F' U2 B' D2 F // HTR (15)
D2 L2 D2 L2 F2 U2 // leave E slice (21-1/20)
+1 slice (21)

all my DRs were bad

(R) L' U R, (D' B), U2 R2 F U2 F // 11 2c3 4e w/ HTR in 16, 23 opt
B L R2 F' R', B, (U' B' U' B) // 10 4c4, 24 opt
(B' L F' R, U F' B' D F' U' F) // 10 2c4, 24 opt

jfc i missed +5 to DR on (R') L' U R, F B, (L2 D B D B) // 11 2c3 2e with 21 opt
