I'm not responsible for armoers at other events -- regardless of the level of the tournament -- who don't know how to properly run the gabarit or other control checks, or who let weapons slide because they just barely fail. I'm only responsible for the control tasks I am given. The rules state the blade length from the front face of the tip to the guard is max 90cm. I give the blades every chance to fall into the slot on the gabarit, but if it doesn't fit, it's a fail. I don't particularly care if you're a first timer or a world champ/Olympic gold medallist.How do you think the length of an epee blade you're citing (which isn't remotely the same thing as a RoW call) even came to be? A bunch of dudes sat around and said "so what do you think?" and then they wrote down the consensus. But apparently there's a rogue group of international armorers taking a page from PF's book and just doing whatever they want and allowing 91cm blades into competition, regardless of the consensus.
Ask Dan DeChaine if I was wrong to reject any of the weapons I rejected for length, guard, or grip offsett...he'll tell you I wasn't.
