I mean, okay, sure, but here are a few points to consider:
1) UTSW was 236 median in 2013 (sourced above) - I highly doubt they've been going down, particularly when they've been going up for the past few years (as has the national median)
2) Standard deviation is still 20+
3) Without sources, this doesn't really matter anyway
4) Median MCAT for UTSW is 33-34 while median MCAT for UTMB is 32 so they're not that different
5) Comparing schools in Texas might be different from comparing schools in other states due to their unique application system and where students with multiple acceptances matriculate (for instance, because of the Texas system, people will really only apply OOS if they have numbers for top schools, so you have a "brain drain" out of Texas to these top schools, so even if the median accepted MCAT for UTSW is 34, their matriculant average may be much lower because the tippy top applicants are getting scholarships to other schools or acceptances to schools like Harvard)
