no blitz chess ratings over 950?
I think opponents are automatically selected within a range of +/- 200 points, and when I was around 700 or 800, I often met opponents that were that much higher or lower than me. (and yes, mostly losing against a +150, but sometimes winning, or more embarrassing, losing against a -150). Now at 900, I still meet 700 or 750, but I can't remember that I ever met >950 (and I do play quite often).
