Where the hell have you been andy? The vast majority of IPSC shooting today is done freestyle with the most important elements being able to shoot on the move, shoot upon arrival, shoot as you are leaving, shooting though low ports, shooting around barricades, and so on. As for moving targets, there are more movers in use now than ever before. Movers on cables, swingers, drop turners, bear traps, texas Stars, wind mills, etc. Dude, you really are showing your total ignorance this time around.
Oh, and on the concealment deal, IPSC guys don't draw from concealment, but the vast majority of IDPA is done from concealment. In fact, the single most practiced drill for IDPA shooters is drawing and firing a shot from concealment, often times while moving. You need to get a clue. If you are going to shoot off your big mouth in your continuing effort to alienate people, at least talk about something you know about.
