Wow, nice solve on the second Jacck! And the first one too!

Scramble: R' U' F U2 F2 R' B2 R B2 L D2 B' D F R F' D L' R D R' D R' U' F
Solution: U R2 D B2 U' R D' L2 D U' L2 B' L' U' L' B L F L' B' L F2 U' (23)

First I have found this backup solution:
D L D' F' R' //EO (5/5)
D2 F B' U2 L2 D F * //DR (7/12)
(D L2 B2 U' L2 U') //HTR (6/18)
(B2 D2 R2) //3e (3/21)

* = F2 L2 U2 R2 B2 L2 D2 R2 (8-5/24)

And then this (same solve as Sébastien):
(U F * U L B) //EO + pair (5/5)
(L2 U D' L2 D R') //DR (6/11)
(U B2 D' R2 U') //3c (5/16)

* = F L' B L F' L' B' L (8-1/23)

The optimal finish from this DR also given 23 final, and it is findable, although not obvious imo:

(D2 R2 D' L2 F2 U' L2 D R2 U R2 D)

Interestingly, both solves start from a sub-optimal 5-move EO... and those are the only two sub-optimal EOs that I tried!

Scramble: R' U' F D' B' U2 R2 B2 F2 L F2 L2 D2 R2 D' L U' B D2 R F U2 R' U' F
Solution: F2 D' B2 U2 F2 L2 R2 U R2 U' F2 L D' R2 D U R B' U2 R' B (21)

(B' R U2 B) //EO (4/4)
(R' U' D' R2 D L') //DR (6/10)
F2 D' (F2 U R2 U') //HTR (6/16)
(R2 L2 F2 U2 B2) //FIN (5/21)

Originally I had found the HTR as F2 D (F2 D B2 D'), which made it harder to find the easy finish.
Optimal after EO!

(L) //Even more pairs (1/1)
* R' F2 U2 R' //321 (4/5)
F2 R' //Square (2/7)
B2 R' B F2 L2 F //F2L-1 (6/13)
U' L U2 L' //3c (4-1/16)

* = U' L2 U R' U' L2 U R (8-2/22)

23, 21, 22 = 22.00 :O
