How PFF grades all positions

If we were watching a game together you could not tell me which throws were +1 and which ones were +2.

That's why grades are not released right after a game.
They go back and view each play. Check to see if a WR was open or not, did the player get killed after catching the ball, ball placement, velocity etc. Each little positive check eventually changes it to a +2 and negative checks lower it, ie INT's Sacks etc.

It is a fairly complicated system, but I'm not sold on it being the ULTIMATE guide. Take it for what it is, just another way to generate stats and see if a player is good or not in a certain scheme.
