Scramble: R' U' F U F' B' U L' D R F2 D' U2 B' R2 F U2 R2 F' R2 F2 L2 D2 R' U' F
Solution: U' B U B2 F R2 U2 F2 B2 U' F' D F' U2 F D' F' U' B2 U' F2 R2 L' U R' F (26)

(F' R U' L) //EO (4/4)
(R2 U [1] F2 U2 R2 F') //223 (6/10)
(B2 U' B' U) //5c (4/14)

[1] = U' F2 U B2 U' [2] F2 U B2 (8-2/20)
[2] = U2 F D F' U2 F D' F' (8-2/26)

I also had Sébastien's skeleton, but I did not try inserting it.

Scramble: R' U' F R2 D F2 R2 D' R2 U L2 B D' R' B' D' F U2 B2 D2 R2 D R' U' F
Solution: L R F R' D F L U2 D R D U2 L B' U' D L F' D2 U2 R D B2 U2 (24)

L R F R' //Square + pairs (4/4)
D F L //321 + square (3/7)
[1] U' F D' [2] L D F2 U2 //Solve corners (7/14)

[1] = E' //To 4e4x (2-1/15)
[2] = U2 D2 B R' E' R B' U2 D2 //Solved (10-1/24)

Optimal finish after 321 + square:
D' L2 D F' D F2 U2 F R U2 F2 D B' U' (14)

Scramble: R' U' F L F' D2 R' D' B2 R L D R' F2 D2 R2 F2 D2 L2 U L2 B2 R' U' F
Solution (1hr): R2 F U L R' F2 L' R D' R2 U' R2 D' L2 B2 L2 B2 L2 U' L D L2 U' D B2 R (26)
Solution (not time limit): R2 F B2 R2 B2 D2 F2 L2 U' F2 U' L' R D2 L R' U' L D L2 U' D B2 R (24)

R2 F //EO (2/2)
(R' B2 D' U L2 D' L') //DR (7/9)

Funnily enough, I have found this DR starting with the EO F' B U2 B (and the same moves on inverse).

Solution 1 (1hr):
(U B2 [1] D R2 U R2 D [2] U) //5e (8/17)
[1] = B2 L2 B2 L2 B2 L2 (6-2/21)
[2] = R' L F2 R L' U2 (6-1/26)

Solution 2 (no time limit):
(U) //Possible start for HTR (1/10)
B2 R2 B2 //Square (3/13)
D2 F2 L2 //HTR setup (3/16)
U' F2 U' //HTR (3/19)
L' R D2 L R' //Finish (5/24)

I also had this nice blocky start:
F' B U2 B //EO + square (4/4)
U F2 D' L' U //321 + square + pair (5/9)

26, 24, 26(24) = 25.3(24.6)
