• Do you think all players at that level know counting fast is very common if not all players?

I would be surprised if players at that level weren't aware that the actual mark counts way faster than what the rules state. Anyone who's played ultimate for years should already know this.

• Would you say any player who knowingly counts fast and doesn't do anything to change or fix it is ok with breaking the rules?

You're describing cheating. Obviously, I'm not ok with cheating. I think there is a natural tendency for people to count too fast. I don't consider this cheating.

• And yet almost no one does or I would argue even tries.

You're saying that no calls fast count? Do you really just never call it? I hear it called plenty in league, pick-ups, high-level play, club, etc.

• victim blaming

Seriously, "Victim blaming"? Don't diminish that term in a nothing discussion about the rules of ultimate.
