I have no empirical data to back this up, but I have a gut feeling that the averages are somewhat misleading...
People aren't (usually) going to get accepted to an MD/DO school with less than a ~26. That means, 26 and lower are typical pod school applicants. Due to the small volume of applicants per cycle, I imagine that the "average" GPA and MCAT are not as competitive in pod school and the acceptances go much lower than this (perhaps a whole standard deviation?) just based on the fact all 24, 25, and 26s won't get in anywhere else, so they raise the average, but do not complete the class sizes. So ALL the 21, 22, and 23s fill the classes without having a real problem getting accepted.
This post was confusing and I apologize. I have no evidence for this claim, except that there is a large disparity between DO admission and Pod admissions which leads me to this conclusion. Anyway, I think you'll be fine!
