It’s also a poor proxy for what really matters: door to door them.

UPX runs every 15 mins.

If you don’t plan at all, you’ll have an average wait time of 7 minutes. How bad is that?
Average wait time of 7 minutes if the trains follow the schedule exactly and don't bunch.

If things are allowed to drift randomly, you end up approximating the exponential distribution - which has an average wait time of 15 minutes for 4 trains/hour.
