An ill timed train throws a huge monkey wrench into an already poorly running machine.
I cross those tracks M-F to work in MM, and two trains go through there around 4:15pm M-F. One of these trains stops at the station and the gates stay down the entire time the train loads up and gets going. If I leave at 3:55 from work I can normally get through beforehand, but if I leave at 4:05 then I get stuck for 15-20 minutes sometimes. I know somebody at work that leaves at 5:00pm, and there is a 5:15pm train that does the same thing, but being 5:00pm the problem is even worse.
However, I do think commuting into MM in the morning and out of MM in the evening may be worse than they other way around.
