That oak one was pretty good, for oak. I don't think it was ALL that fast, but it gave me low set, and high-ish draw-weight.
But, generally, I don't even pay attention to this on most woods, because I'm just happy to have a clean-ish stave worth working, unless I'm looking for a ring to chase.
I'd be curious to know the answer, but it seems to me that this factor would be way down the list of things that boost performance, below design (incl. choosing the right design for the stave and species), execution of good tillerr using low-set methods, mass placement and control, heat treating, etc....
