+1 definitely agree. I did a lot of my own comparo's from Ready to remove that variable. Any of his 7 yard standards other than immediate incapacitation can be pushed hard enough to see what if any diff manifests, in my experience anyway. Just two to the 3x5 wasn't enough of a string for me.
The Test @Mike C used as a benchmark might be useful as well. I preferred the balls out 7 yard speed drills for this purpose.
