I agree. This is the only factor I can think off too, you lose some bound info.

Yet, I ran a couple of WAC tests at very short time controls, with and without
LE. And kept track of the average depth that was reached. In that quick test
NPS went up, but the average depth stayed the same!

So it seems what you win in speed, you lose in bound info, net result zero? At
least in this case. I will rerun it more accurately, at longer tc.
