LizzyM score

Does anyone have any experience using the LizzyM score / can anyone speak on how indicative it is of your compatibility for a school? It looks pretty legit, but the list I got was different from the one I've compiled just from my own digging. I'm wondering if I should scrap that in favor of the the LM list instead. My MCAT score was a 516 so before, I was mainly looking at schools with a median either at or one-two points above mine, and then looking to see if they matched w my GPA.
