Ok close enough.
Again, DOs can choose to hide their scores if they bomb USMLE and many do so (there was another 2 posts like that just today). Since only the top of the crop of each school take USMLE it's no surprise 228 is the average. If everyone took it it would be far lower. Even "top" schools like MSU only have an average of 217-220. All of these things taken into consideration bring up the average.
If we used the same formula for MD by only using the top 60-70% the average would undoubtedly be 240+

My educated guess is the schools with >506 MCAT average are the same schools where the top half of the class is bringing the average up. I know for a fact from friends at some the weaker school that their class average was <215 with a significant percent not taking it or taking it twice.
If EVERY DO school was averaging 220+ you bet your ass they would brag about it. The fact of the matter is schools like KCU, PCOM, AZCOM, Touro etc are bringing up the average, the top 20% at every school is probably doing decent, and most at the weaker schools like ICOM, CUSOM, KYCOM, LMU, are not breaking 210
I don't think anyone is fooled that matriculants with lower MCAT/GPA somehow turned into amazing test takers - and that's okay. I don't judge someone's ability to be a good doctor based on their step score. I could care less what school you went to. My PCP is a Caribbean grad and I absolutely love him. However, we all need to be transparent and there must be standards. We can't collectively fight against scope-creep when you have some DO schools that have virtually non-existent rotations (I literally witnessed this from my friends and their classmates who stayed home all year long)
Otherwise, what's stopping NPs and PAs saying "oh, well some medical schools aren't even doing all that much so what makes them different than us?" Some of the top PA students at my sister school could run circles around some DO students. Take NinjaNerd (From youtube) for example. He's a PA from PCOM and his basic science knowledge is better than mine and probably better than that of many med students.
