Are these your definitions of those terms?
unadjusted yards per pass play = (total passing yards) / attempts

Either yards per pass or net yards per pass play (subtract sack yardage from total yards and add sacks to attempt) also correlate highly. They don't take interceptions into account, though.

pass success rate = completions / attempts

No, that's completion percentage. Success rate is the percentage of plays that are deemed "successful" based on the down and distance. There are various sites that track success rates by their own definitions.

My equation was intended to be silly to make a point. The point being that you can manipulate equations to get a desired result.

And what's the point of that?

ANYPA is defined as passing efficiency by a group of people. Stating that it is an absolute measure of passing efficiency is misleading.
|
Nobody ever said it's the only measure of passing efficiency.

The point of my equation is that randomly defined equations can be wrong even if they correlate to a set of data.

So are you saying that ANYPA does not measure passing efficiency?
