I know that this has been talked about before but here is my experience. Until yesterday I hadn't touched my pistol in three months, no matches no practice. This going from shooting almost every day.
Shot a six stage steel challenge match yesterday and came very near to shooting a personal best time.
Maybe I "forgot" some bad habit I had picked up, maybe (probably) shot better because I had no hope or expectation of shooting a good match.
It was interesting to me anyway.
