Okay, while I haven't taken the bus I'm a long time, or even in this city, but wtf?!?

I am genuinely curious, do they do some weird peak hours/dynamic need system without an actual schedule? I didn't notice anything on their site. I haven't been a regular bus person in nearly two decades, and that was on the west coast, but I honestly can't fathom a transit system that doesn't run with regularity... So many problems here.
