my opinion:
no. your 522 is no different than a 526. once you get into the 99th and 100th percentile it really doesn't make much of a difference. that 522 won't even get you into a T10 anyways. what i mean is that the 522 gets your foot in the door, your app on a desk. rarely does an average score do that at these schools. so great job there. but the stats alone mean nothing beyond accessing the chance to get in there. you better be stellar in every aspect or your T10 chances aren't great. they have the luxury of admitting the best of the best, and the scores at the top there aren't the distinguishing factor when most have them.
some rough math:
85k people take the MCAT per year. about 6% score 518 or above, harvard's average is 520.5. let's assume 518 is still competitive enough for HMS acceptance. so 6% of 85k puts us around 5000 students per year, not accounting for any previous year's testers applying later or reapps with same score.
there's about 1200-1500 students who matriculate into a T10 per year. so at best, 3800 students scoring 518+ don't attend a T10.
clearly, the excess amount of high scorers and limited T10 spots means that 522 isn't good enough on it's own. HMS is actually lower average than a good amount of the other T10s, just going to show how important everything else is. what makes you special to a T10 isn't your stats, everyone has those that are competitive. it's everything else.
there's a lot that isn't considered here, but it's close enough to prove the point.
now, beyond T10s: you have a fantastic score!! play your cards right and you should have no issue getting into a school. but be realistic and make sure you don't apply too top heavy. for those top schools, there is 0 guarantee, and it hurts to see some of you SUPER smart people with incredible stats make a blunder by only applying to the top schools and not getting in. you have a VERY high chance of an acceptance, barring any red flags, but don't forget the brutal aspect of the top medical schools just because your stats are great.
