What calcs? You didn't show any sort of statistical model proving your point? You found a trend that supports your argument, that's all. Doesn't prove crap, nor does it predict anything that's going to happen in the future.
You want to prove something? Show the sample size with Fox alone vs Hali alone. Show the pace differential. Show the opposing team offensive numbers. Even then, what the hell does that show? Both guys have played with vastly different supporting casts alone and you have to model for opponent strength as well. AND I doubt there's enough of a minute sample for any of this to matter anyway.
Thus, gibberish.
