My masters group is not coached. Only about 10% of what I've learned about starts, strokes and turns was learned from other swimmers and the rest I learned online. I'll be on vacation next month and will swim with a coached masters swim team. I don't know what to expect! I've emailed the coach and he knows my ability level; I think I've bothered him enough.
I know they're all different, but tell me what yours is like!
