B' L' D' R F' // double jzp lol
R F2 D2 L' U2 L // 11 2c3 4e
D' R2 B2 D' R2 D'
R2 L2 B2 // 20 E lol, +2 =(

Found this at like 15 minutes from checking like 2 htrs on the 2 dr variations on normal i wrote down

Also had this but boring:
(L' D)
L B (U2 L' D2 L B') // 9 2c4
(L' U2 L F2 L' F2 U2 R)
(B2 D2 F2 U2 L2) // 22

Other sub11 drs:
B R' L' U R'
D2 B2 U2 F U // 10 2c4

B' U2 F' D
F' L R2 F2 R B // 10 2c4

Apparently you can get a 21 from the double jzp eo, should've checked the ...F R' F2 D2 L B2 L variation on inverse:
B' L' D' R F            // eofb      (5/5)
                        // arlr-eofb (0/5)
L' U2 F2 R' F2 L2 B2 L  // drud-eofb (8/13)
B2 U F2 R2 D' F2 U' R2  // fin       (8/21)

There's also this but 0 pairs on normal moment:
(L' D')                           // eoud       (2/2)
B R'                              // rzpfb-eoud (2/4)
(B' R2 D2 R2 B R')                // drfb-eoud  (6/10)
(F' U2 B2 U2 R2 F' L2 B U2 B D2)  // fin        (11/21)

U' R' U' B
U R' B2 D2 L' U' // 10 2c3 4e
D2 R (F2 R D2 R')
(F2 L2 U2 B2 D2 R2) // 22-1 M, +1

Ugh, 20 22 22 and the 20 is on a doomed scramble and the other 2 had 3movers

Ah yes, how could i miss that(the dr is pretty reasonable to find considering L D rzp on the non-extended eo is good on inverse, but +9 on 2c4? come on):
U2 B2 D B                   // eofb       (4/4)
L D                         // rzplr-eofb (2/6)
(L' B2 L' U')               // drlr-eofb  (4/10)
(F2 L' B2 U2 L' F2 L B2 L)  // fin        (9/19)

Other:
B2 D B
L D (B2 L' U2 R' U) // 10 4a2 2e

B2 D B
U L D' F2 L2 U' L2 U' // 11 4a1 4e

U B2 D B
L (D' F2 D' R' U2 R) // 11 2c3 2e

also this scam:
(U R D2 B D)
F' L2 B D2 F B2 L // looks like +3 to htr but actually 12 4b5

(U F' U)
(R') B R' // fucking jumpscare 6 2c5
(B' L2 F) R2 D2 B L2 B' U2 F'
L2 D2 L R' D2 L' R' // backup 22

I spent like 15 minutes on these 2 extensions i thought were 8movers, ugh:
(U F' U)
(R) R U2 R' B R' // 9 4b3

Very disappointing after a1, apparently the 4b3 in 9 is 21 opt but i missed the M2 insertion before second qt after switch, and the 2c5 is 20 opt with these, come on:
nissy-# solve -t 64 -M 16 R' U' F R U B2 F U F2 U B2 U' L2 D' U2 F2 L' U' F' D2 F2 L2 F R' U' F (U F' U) B
R D2 F U2 R2 B2 U2 B U2 L2 B' U2 F D2 F R (16)
R D2 B' U2 F' U2 L2 D2 L2 B' U2 B D2 F U2 R' (16)
R L2 F' D2 B R2 B' U2 B L2 D2 F' U2 F2 D2 R (16)
R L2 F' D2 B R2 F' L2 B D2 R2 B' U2 F2 D2 R (16)

The only reasonable 21 i see from nissy is this, it's a +1 extension of an htr i had on inverse:
R B2 D2 F2 U2 F D2 L2 F' R2 U2 F' U2 F D2 F R (17)

Would've been better off not finding the 6mover honestly, there's this other 20 but i straight up missed the eo:
R' D2 F B (F)                       // eofb       (5/5)
(R)                                 // rzpud-eofb (1/6)
U L'                                // drud-eofb  (2/8)
B2 L2 U D2 L2 F2 U' F2 U2 F2 L2 F2  // fin        (12/20)

Also had this:
F' R
(U) U2 F D2 F D // 8 2c5

F' R
(U) U2 D2 F D2 F D // extend: 9 4b5

F' R
(U) U2 F2 D F D F2 D // extend differently just for 10 4c4

(U F2 R F B) // 4c6e with 4 pairs(+ FB eo) so switch
D2 R2 D' R F2 L' // 11 4b3
(U2 F2 U) // fake htr

Flip:
(U F2 R F B) D2 R2 D (U2 F2 U) // 11 4b2 2e with 16 variations
R2 F2 R' D2 L
U2 D2 R2 B2 U2 // 21-1 M, miracle +0

you can do this with this solution which almost works but it unfortunately it doesn't:
R2 F2 L' F2 R [U2 D2 L2 B2 U F2 U2] F' B' R' &

[] = R2 F2 U' B2 D2 // 2e2e in 17
& = M2 // 4x on M in 18, basically slice in 18, but it's doomed cause the dr portion is all F2s: R2 F2 L' F2 R' F2

Also found another cooler 20 later(the one i submitted):
(U F2 R F' B)
D2 % R2 D (D2 B2 U')
(D2 B2 R D2 L)
(F2 L2) // 18 2E2E

% = D2 R2 L2 U2 R2 L2 // +2/20

Has to be one of my favorite solves in a while, optimal from the first 3 moves

These are the only 2 sub22s mallard finds so i'm very happy with a 20(i didn't see the rzp for the first cause i already had a 20 and wrote but didn't check the second eo):
(B D L B2 R)                     // eolr       (5/5)
(B)                              // rzpud-eolr (1/6)
U L2 B                           // drud-eolr  (3/9)
R2 F2 U2 B2 U L2 D' U2 L2 D' R2  // fin        (11/20)
Solution (20): U L2 B R2 F2 U2 B2 U L2 U2 D' L2 D' R2 B' R' B2 L' D' B'

B' (B U R F)                   // eofb       (5/5)
(U)                            // rzplr-eofb (1/6)
F2 L' R2 U'                    // drlr-eofb  (4/10)
F2 U2 L2 U2 R' U2 B2 R' U2 R2  // fin        (10/20)
Solution (20): F2 B' L' R2 U' F2 U2 L2 U2 R' U2 B2 R' U2 R2 U' F' R' U' B'

L' D L U' R'
D F B L2 F' U' // 11 2c3 4e
(F L2 U2 F D2 F)
(B2 R2 D2 R2 L2) // S "21", +1

All mallard's sub22s are premoves on 5movers so nah

Cool dr but of course it's 2c5:
(F' L B' U R')
(U2 F2 U B F2 D) // 11 2c5

Also:
(U2 D' F)
U D' L' U2 R' B2 U // 10 4c4

(U2 B2 D' F')
(D) R' U2 F2 D R' U // 11 4c4

[R L] (U2 F2 R')
(U2 B2 U2 L2 F' D) // 11 2c3 4e
(F2 U2 B U2 F D2 F')

[] = D2 R L D2 B2 D2 // 22 S, +0

Also:
R B' R B L
(U2 B2 U L2 B')
D R2 D L2 U R2 U'

Other:
(L U2 D' F R)
R F2 F D' // 9 4c4

D (D B' L2 D)
L2 F2 R' U2 L' B // 11 2c3 4e

Didn't write this eo, other than that 22 seems the best you can do somehow:
F (D' L R' B)             // eofb       (5/5)
                          // rzplr-eofb (0/5)
B2 L' R2 U' L2 U          // drlr-eofb  (6/11)
F2 U2 L' F2 L B2 U2 L D2  // fin        (9/20)

L' (B' D' B L)
(B' D2 B L2 D) // 10 2c3 2e
B' R2 B' R2 U2 B'
U2 L2 B2 D2 L2 // 21 S, +1

L U2 D B
L2 D L2 U2 L' D // 10 2c3 4e
(R F2 R F2 U2 R')
(F2 B2 U2 R2 F2 D2) // 21 M, +1

There's surely a 21 from one of my drs, but there are just too many decent 10movers. Edit: there isn't, only from a +1 extension of the dr from final

I am actually so stupid, how did i find a +1 to rzp shift 5mover but not the direct +2 to trigger, lmao:
L D U2 B'                       // eofb       (4/4)
                                // rzplr-eofb (0/4)
R F2 D B2 D'                    // drlr-eofb  (5/9)
R2 F2 L U2 F2 U2 L R2 B2 L' U2  // fin        (11/20)

There's also a 19 if you extend by 1(flipped from the output):
L D U2 B                // eofb      (4/4)
F2 L                    // arlr-eofb (2/6)
(R' U2 D2 R B2 L')      // drud-eofb (6/12)
(B2 D2 L2 D' L2 D' F2)  // fin       (7/19)

Lol, found this at 13 minutes. Also a less silly 23:
(U' B D' L)
(R2 F R2 F' D' B' U')
(B' U2 B' U2 F U2 B2 U2 F')
(L2 U2) //22 S, but +1 with both ways of solving 2e

Missed rzp on (F2 R F U) for a 21, ugh

B' D B2 D2 F U F' // 10 4a2 4e
U (L2 B2 U')
(R2 U2 F2 B2 R2 F2) // 20 E, +1

Found at 30 minutes and couldn't improve, bad. Missed U2 after (B U2 R F) for a 19 and (B R2 U') (F) rzp for a 20, ugh

Saw the 3c6e from the 3move eo of course but didn't try fixing the E layer, oops. Also saw that (U D' B) was also a 3c6e but didn't see the setup on normal
