first i can't answer your question for organized clinics but i can tell you what i did when i started ipsc years ago. after my first match where i failed miserably. i snagged a couple of the guys running stages who were decent in their own right in the sport and asked them questions but what transpired was they agreed to work with me at my club (pelham) for a few saturday afternoons. they started with like a classroom where they could explain match safety and certain nuances of the sport and gave me a chance to ask questions. then we moved to the pits and learned how to draw, grip, sighting. we just did all this in slo-mo helping me with the general idea. we moved on to drills, awareness, putting it together under time restrictions. etc. etc. you know where i'm heading with this. best part, they were happy to do it, i made a couple of friends, range buddies and squad mates for future matches and it cost....several rounds at the local tavern when we were finished each day. just what happened to me. good luck. and yes, i did improve, still sucked, but actually managed to win a stage or two.
