"Pull" of trigger these days is hardly well defined. One rearward motion? A lot of guns I've seen can shoot from a sideways tap or wiggling it forward at an angle, so if you counted each way it went then you might very well have 2 or 3 shots per "pull." A single trigger Cocker these days is about all you see with what you'd call a pull. Tap? Motion? Touch? That might be getting at it. Trigger bounce can be pulled in a simple rearward motion to one shot per pull, so it's legal. Why complain? Honestly, if you have nothing better to do than whine about how the other fellow's trigger moves, you deserve to be shot out. Preferably close. Concentrate on wiping or playing on--those are more solvable and clear cut issues that actually deserve attention.
