NE1 hear of this rating site, CXRchess?

They analyze your games and give you graphs showing your weaknesses and strengths. Just wondered if anyone here uses them and what you think of this site?

I took a look at it, and I admit it made me curious. I have used statistical analysis for my own games, and sometimes learned some interesting things.

For instance, a many years back I looked at all my games as white, and I learned that I had a better winning percentage against players over 1700 than I did against players below 1700. There were over 40 games against each, and I deduced from it that I tend to play hard "up" and and slack off when playing "down".

It would be interesting to see if anyone had tried it.
