I have a question.
I solve 4x4 as follows:
Solve Centers 15 seconds
Pair edges 2 at a time 40 seconds
Solve as 3x3 30 seconds
Now, please don't tell me to learn yau, or 6 at a time pairing, or better parity algs, I am not asking how to get faster. I am just wondering, with the method I use how fast could it get without changing anything?
