im pretty much in the same boat as you, been licensed about a year and just started messing with cluster spots a few months ago. the filtering thing was confusing me too for a while. one thing that helped me was just watching the spots for a band i knew was open and seeing which ones i could actually hear — after a few sessions you start to get a feel for whats realistic from your location and what to just ignore. i tried like four different apps before settling on one i actually like, some of them are just ugly or dont update fast enough. still havent found anything perfect tbh
