i am sure that most of us do just that. i usually set my trigger at 2lb 6oz just to be sure... but there are quite afew of us that don't own trigger scales or weights and are just hoping that we are okay. and... i wouldn't consider someone setting their trigger right at 2lbs to be pushing the rules. to the contrary, that individual would be playing by the rules... inviting problems perhaps, if the scale at the match is a bit off, but certainly not "pushing" anything.
