Important point is that correlation coefficient is merely 0.738 for blitz rating-Elo. Meaning that only about 50% of variation in chess.com rating is explained by ones Elo rating or the other way round. Rest is explained by differences of the two different environments.
and here is the Elo prediction formula from blitz rating, which seems to be the most reliable predictor:
483 + 0.769 * Blitz = FIDE rating (+-193)
So an error of 200 points. So you compare, as long as you undersstand that result might be off by 200 points and is unlikely to hit the target within 50 pts.
And chess.con Std to Elo has corr. coef. below 0.6 meaning that only 36% is explained by rating in one pool and rest is something else
It was a good link and it supports Adams original point that chess.com blitz ratings are lower than OTB rating by about 150 pts.
You're obsessed dude. Cheaters aren't playing bums like us often enough to notice. The ops reckoning ain't dead, but it's close enough.
Cheats are playing at all rating levels. Intermittent cheating, is quite common. They use their engines during small parts of the game. Often times this is enough for them to win. Sometimes not.
And when they "turn on" their engines, they (sometimes) start to taunt you in the chat box. It's all very entertaining. Except then, you typically lose.
