Well the wife & I took care of cooking last state match - while one gent was SOing who was not a certified SO - I really don't care, for the most part I do not like most of the people at that range, its close is the ONLY reason we go.
The SO's at state matches have the advantage w/o question of being in on each stage prior to shooting, often actually in on the planning stages, while regular shooters do not have the luxury of getting a mindset, at least thats how things are done here from what I have been involved in, thats an advantage for SO's over the regular shooters.
Do I think the BJ buddy system comes into play, it does to some extent, SO's should not shoot a match they help setup in all fairness to folks who do not have first hand knowledge of each CoF.
just an opinion, we shoot for practice & have no interest in a paper prize.
