I only had this 5 mover written down cause too many variations but seems interesting so:

(R L' F2 U2 B') // EO (5/5)
(R2 L2 U' R) // DR, 4b2 2e (4/9)

Much better

F2 L2 B2 U B2 D // HTR (6/15)
F2 B2 R2 D2 F2 L2 // finish (6/21)

(R2 B U') // EO (3/3)
F' // JZP (1/4)
R' D2 B2 U2 D2 L' // DR, 2c3 (6/10)
(R2 B R2 F' D2 F) // HTR (6/16)
(D2 L2 B2 U2) // finish (4/20)

Had a slice in 20 from the other DR variation (22 opt from that) and then I checked the right variation nice

(D) B U // EO (3/3)
F * R' L // DR-32 (3/6)
(F R' F' R) // DR, 2c3 2e (4/10)

* = B2 // extend for better cases (1/11)

B U2 B' U2 B' // HTR (5/16)
D2 L2 D2 R2 B2 // finish (5/21)

IDK what happened with the easy 19... 404 not found

B D2 R' F2 U2 L' // DR, 2c3 (6/10)
B L2 B U2 B // HTR (5/15)

bad subset so extend (wait a minute, did I do the same last attempt...?)

D' L' F' U // EO (4/4)
R2 F' D2 R2 B2 L U2 R // DR, 4a1 4e (7/11)

Had a 22 at 45 minutes and then I found this pearl.

(B2 D' L' U) // EO (4/4)
(D2 F2 R' L2 F2 R' F) // DR, 4b2 4e (7/11)
R2 D2 L (U2 D2 L') // HTR (6/17)

(D2 L2 F') // EO (3/3)
(R') // DR-44 (1/4)

L2 D R2 F2 D' L2 D' // HTR (7/17)
R2 B2 R2 D2 B2 // Leave slice (5/22)

Slice in +0

Optimal is 20 and there is a 19 from ext...

(F' L B2 D B) // EO (5/5)
([U R' L'] D) // DR, 4c3 (4/9)
R' B2 U2 L2 U2 L' U2 F2 L' // HTR (9/18)
U2 // 2e2e (1/19)

[] = U' F2 R2 F2 U2 R' L' U2 // (8-3-2/22)

Interesting

(R2 B U' F') // EO (4/4)
(U) // DR-44 (1/5)
(B2 L' B2 R D') // DR, 4b2 2e (5/10)
(R2 U2 D2 B2 R' B2 R) // HTR (7/17)

U2 B2 D' L2 B' L2 F // DR, 2c3 (7/11)
U B2 L2 D B2 L2 U // HTR (7/18)
R2 U2 F2 D2 // Leave slice (4/22)

+1...

B R' B2 L' // EO (4/4)
U' D2 L2 D' F2 U' F' // DRext, 4b2 2e (7/11)

Slice in +1

I'm glad I tried this extension quite early instead of trying other stuff.

(D) B R2 U' // EO (4/4)
L // DR-44 2p (1/5)
(R2 F2 R2 B L2 F L') // DR, 4b2 4e (7/12)
(D2) // rescrambling but solved itself so went on normal and searched for 4qt (1/13)
F' R2 F U2 F U2 F // HTR (7/20)
R2 // LOL SLICE (1/21)

+1 for 22.

Had 10+4a2 variation hell but luckily I found this before trying to solve that crap. Didn't find the 11+2 from 3move eo sadly.

(D' B' L2 R U') // EO (5/5)
B2 D2 L B // DR, 4b2 4e (4/9)
(R2 F2 D2 L F2 U2 L) // HTR (7/16)
(D2 F2 R2 F2 B2 U2) // Leave slice (6/22)

Slice in +0


Optimal is 21 in 4qts

(F') R2 L2 F // EO (4/4)
(R') // DR-44 (1/5)
(F2 U B2 U R') // DR, 2c3 (5/10)
(F2 U L2 F2 B2 U' L2 U') // HTR (8/18)
(F2 D2 R2 B2 L2) // finish (5/23)

Optimal from DR is 22 but very hard to find (Double slice) 

D (F' D) // EO (3/3)
L U2 L2 R F // DR, 4c4 (5/8)
(L U2 R U2 R2 U2 F2 L U2 L') // HTR (10/18)
(F' B' D2 F B) // Leave slice (5-2/21)

Slice in +0

Optimal from DR and my DRs but there are better findable solutions...
had a 9+4, some 10+5, 10+1 4e (21opt), 10+2.
Didn't think about trying to JZP it:

D' (F' D) // EO (3/3)
R2 U2 L' // JZP (3/6)
F' L2 D2 F' // DR, 4b2 2e (4/14)
(B2 L' U2 R') // HTR (4/10)
(F2 R2) // S slice (2/16) -> +2 for 18

(F) R' U2 F' // EO (4/4)
L // DR-44 (1/5)
(U R2 U2 F2 D R) // DR, 4b2 4e (6/11)
U' (R' L' B2 R' L' U) // HTR (7-2/16)
(B2 D2 R2 F2 L2 B2 R2) // finish (7/23)

another mid scramble imo
