Recently, I've started learning Ortega for the 2x2x2 (You know, make a face, OLL, PBL).
Seems to me the 2 *worst* PBL cases are where the bottom layer is already solved (it'll be a T-Perm or a Y-Perm).
Most of the other algs are ~7 moves. I can *barely* sub-2 a T-Perm on a good 3x3, a 2x2 is slower. I doubt if I can Sub-3 a Y-Perm on a 2x2x2.
As I'm colour neutral, would it make sense in pre-inspection to *reject* any first-face that solved the entire first-layer (and look for something else)?
Try this for Y
