Because Yau and Hoya build these edges in place.

It wouldn't be a fair comparison if you don't get to the same point in the solve.

Ultimately in means the whole point of this thread is silly. You can't look at the "efficiency" of edge solving in isolation from the method. Maybe edge movecount is lower, but centre solving is significantly impaired. Maybe edge movecount is much higher, but the cross+F2L is completed at the end. Efficiency could only truly be looked at when comparing whole solves and looking at a range of factors.
