this is the opposite of "impartial", just fwiw. adjusting scoring based on subjective variables is quite partial

Selecting variables to measure and give weight to a population from the onset may incur some testing bias. The "impartial" I was referring to, was the bias that everyone has for their favorite/least favorite QBs.

QBR does a much better job of selecting and weighing critical variables from the onset. Comparatively, the traditional QB rating takes a very limited snap shot and uses variables that don't correlate as well to performance.
