The usual MPBR drill does not take into account the grouping capability of the rifle. If in that example, your nominal drop takes you 4" low at 325 yards, that is for the average shot. If you have the proverbial MOA rifle (+load +position +hold) then you might well strike another 1.7" lower still; 5.7" off center. Does that matter to you? (Yes, I know you might strike that much higher and be closer to center, too; but you have to figure the worst case.)
