This is a made up statistical analysis for the efficiency of an offense under a quarterback. I made it up. I'm pretty sure nobody else has something exactly like this. It's a basic system, but it works to show how an offense progresses under a particular signal caller. If somebody else has done something like this before (which is likely), sorry not sorry for copying it.
First, let me explain
I want to say that this is indeed different that a quarterback's rating. This doesn't go through yardage totals and completions or how well they ran the ball.
