this really doesn't come down to average rating, more like personal preference as to whether or not they like to resign or not, and if that person truly believes they can get a draw no matter how much their losing the game.....
I don't agree. I have been following other threads on this topic quite closely and there does seem to be a distinction in the rating levels. I just want to get some real numbers. In my experience players over 1700 usually resign and players under 1500 usually play on. My rating hovers around 2100+ for reference.
I'd say about 50% of my games(800-1400) have either me or my opponent resigning.
