Good is based on your performance against other players you'll compete with for a roster spot. Meaning, if you want to play P4, you need to show success against other P4 athletes on a consistent basis. Having an outlier performance the one time you play against that level isn't enough to move the needle at that level. It's very different to perform against solid teams consistently and #1 pitchers game in and out.

I'm not saying you're wrong; I'm saying it isn't easy to prove it definitively.
