Taking away whether it is allowed or not, I think most would agree the point of pressure plates placed in this manner is for foot activation to simulate target movement starting from the point of the shooter entering the position. Short of adding more rules to the rule book,it comes down to stage design to negate some of the 'not so practical' gaming. While I generally support the 'freestyle' arguement, I find it a little ironic that some competitors would defend this type and similar action during a match, yet vehemently fight changes that would see .22s and air soft compete... Drama? Is there a shooting sport that doesn't have it's share?
