General question

Okay dear forum, I have my first question for you:

I'm currently mingling around a 1600 rating in blitz, and keep wondering one thing: me and my opponents are at a skill level, where either player knows that with 1+ minutes on the clock, an endgame with at least a rook advantage will be converted. Still, even in far worse than a rook down endgames, people tend to play it out until they get mated, even if there's an obvious checkmate sequence. So my question is the following, to the higher rated players:

When do people start to hit the resign button once they realize they are losing, instead of playing out every single lost position? 1800? 2000? FM level?

I like Jonathan Corbblah and his never resign philosophy.

I don't know if there is a specific rating where players start resigning, but from my experience most players above 1800 resign if they are losing.

@SekiThisIs
I understand that there is some kind of "please resign" philosophy, specifically, a major concern of yours, which exceeds in importance even the fact of improving your game.
I wouldn't worry about it.
And, by the way, the process of converting the advantage it's much more important than asking, waiting or hoping for some quick resignation disposal.

Since it's blitz, people are gonna be a lot more likely to play it out.

It has to do with the time control. In longer time controls resignation makes more sense. In time controls with increment resignation makes more sense. It has also more to do with the rating of the winning side than with the rating of the losing side. I trust an opponent of 2300 rating to know how to convert in time, but an opponent of 1300 not.

when in doubt play it out.. or else resign...

Engines are best players in the world and quite never they resign(also quite never they lose but it is a different story). Even world champ resigns later than early. Probably there is a reason about that. Fight and never give up!
Ps: if you are lonely king vs king and rook you can resign(none will judge you for this) or move fast until checkmate.
