like everyone else said, do it yourself. if you release when you dont think you should have, go up .5 or 1 number until you get the desired release point. also no good tech will just change your din because of legal reasons, they will do a calibration.
PS. as a ski tech, i think its stupid kids like you that are the downfall of our great sport. learn to do easy little things yourself through a process of of trial and error. if its too low, go up; too high, go down
