Found at 55 minutes, I was close to DNFing this one!

(F2 U' B2) //Square + 2 pairs (3/3)
(R U' R2) //Another square, another pair (3/6)
(D') //Break a pair, make another (1/7)
R U' B' U' //2x2x2 (4/11)
D' * F D' F' //F2L-1 + pairs (4/15)
(D' L2 D) //All but 3 pairs (3-1/17)

* = L2 F' L' U L2 U' L F (8-1/24)

Same DR and almost same HTR as Sébastien, I missed that variation and the shorter solution.

(L F D2 R') //EO (4/4)
F' //Simplify (1/5)
(L2 D L2 D' F2 D' F) //DR (7/12)
(D R2 F2 D) //HTR (4/16)
(B2 R2 * F2 D2) //2e2e (4/20)

* = R2 U2 L2 U2 R2 D2 (6-2/24)

22, 24, 24 = 23.33
