I do find it amazing (as an amateur hovering around 1050 or so) that at this rank at a blitz game, I can do about 150 rating better at rapid - sure I get more time to move, but so does my opponent. I would expect at the amateur levels that the ratings wouldn't be so different.
Blitz and Rapid ratings aren't related like that. One could be higher than the other, or the other way around, even by 1000s of points. It just depends where the site wants to set the average, and what kinds of players are playing in that time control population.


mistakes. distractions. turn a higher level player into a lower rated one. it's too ez to start a quick game online when you don't have the time or focus. as soon as wife starts jabbering, or comes home, etc.......I'm going to lose. sometimes you can have the right clear frame of mind to play, and win a dozen straight. Other times without it.....you do the opposite.
