2. With and without limit

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

Same solution as chriscuber123!
(R2 U) //EO (2/2)
(L' F') L2 //222 (3/5)
R B R2 //Square (3/8)
B R' B R D2 B R' //All but 5 corners (7/15)

Skeleton:
R * L2 B + R2 B R' B R D2 B R' F L U' R2

* = F' R2 F L2 F' R2 F L2
+ = F L F' R2 F L' F' R2

I have also found this nice skeleton:

(R2 U L' F') L2 R * B R2 //Same as before (8/8)
(R2 D2 R' B2) //All but 4 edges and 4 corners (4/12)

Which can be solved by conjugation + one move. But the best I could find from here was

* = L' F B R' F R B' F' L //All but 3 corners (8/20)

And unfortunately optimal is 27. I have tried also cojugating to an LL case, but with no luck.
