Games would grind to an utter halt in football if every holding call got called. Same with every touch foul in basketball. It's not always appropriate to stop the game just because a rule was broken. I don't think you analogy of the blown perfect game/blow goal really work because those weren't examples of a ref using discretion, but rather they were examples of refs getting the call obviously and terribly wrong. IMO the argument that every foul should be called all the time is way more problematic than asking for a little common sense and discretion. Prime example: Michael Jordan's push off against the Jazz for his famous last shot. It would be awful if a referee waved off his shot because he pushed off. He would be technically right, but it would go against everything that is good about competitions. Same with the (in)famous Helmet Catch - people where I'm from still complain about all the missed holds during Eli Manning's scramble, but the fact of the matter is that it would have been ridiculously inappropriate for the refs to call a foul on the deciding play of the game.
tl;dr it's not about a formula for how many calls are acceptable, it's about the ref using a little discretion. Stopping the game and pissing off the players for no tangible good is the opposite of that.
I used the phrase "rule lawyering" earlier, because that's exactly what this is. Yes they broke the rules, but it makes little difference. Therefore: let it go.
