I'll try to set the stage. Might miss some pertinent info.
-Level 1 local IPSC match (some here call it a Level 2 but imo it doesn't qualify for L2).
-Shooter does his load and make ready on command from RO, has handgun holstered as per WSB.
-Someone notices a target is not taped.
-RO instructs shooter to put hands on head, which he does.
-RO instructs someone to go tape target, which he does.
-Right after taper clears range, shooter unholsters pistol (no command from RO at this point) and takes a [Edit: checks his dot while with gun in hand], holsters again and gets in ready position.
-RO does the regular are you ready, standby, beep.
-Shooter shoots stage, they score it like normal.
-At some time during scoring or just after shooter hits approve on Practiscore tablet (I'm not sure which, I didn't get info on this): someone points out to RO that shooter unholstered without command before starting the stage, RO decides to DQ shooter.
Can anyone weigh in? I think it's fair to say the RO should have noticed the DQ action by the shooter right when it happened rather than after the stage is complete. But given that he didn't in this case, is an after-the-fact DQ the right call?
