At what level piece losing blunders become more exceptional than regular?

As it stands, a blunder/blunders on my or my opponent's side decides a very vast majority of my games (with opponents rated 1300-2000). I wonder do higher ranked players (let's say 2200+) remember when, at what rating, did the games they played become more strategical and less dependent on players' monumental errors?

Because one unpleasant thing is losing due to huge mistakes, but another even more unpleasant thing is the unrewarding feeling of winning because your opponent made a mistake, primarily not because you were strong but because they were weak.

Obviously even GMs blunder, but when they don't blunder pieces in every game they play. So, when would this 'circus' normally stop?

My guess is around 2400, as at the 2100 level people still hang mate in ones

If I'm remembering right, I would say that Habitual Hangfests stop somewhere around when you're a C player (like say 1500 USCF). And of course I'm talking about slow OTB games there. Bear in mind too that you have to be playing somebody who's gonna notice em all (or most of em). :)

It depends on time control. Obvious (1 move) blunders almost nonexistent in classical, even at 1200-1500. Some mates in 1 may be tricky to see though.

Those kinds of blunders are due to problems of perception and discipline, I agree 1500 player is ligit because blunders like those discredit you.

Depends on the time control of course. 2k rated players aren't making many obvious blunders in rapid or longer.

I'd argue otherwise
