Am I misunderstanding you about the 15 minutes interval?
Every workday I take a one-seat King County Metro bus ride that lasts about 1 hr. The bus starts at a layover facility and ends at a different layover facility.
I don’t see how this 15 minute interval maps to my actual commute?
I don't think you're misunderstanding. I think the person you're responding to is misunderstanding that we were referring to trip end points (layover locations).
