Forget the USCF site for a second. The basic logic behind the system is very simple. That is, if you are rated 200 points higher, you are expected to score 75%. This can be confirmed from this Encyclopedia article on ELO based systems. http://en.wikipedia.org/wiki/ELO_rating_system. If Hydra scores 4.5 points out of 6 games, that's performance of 75%, or *performance* rating of 2937. If Hydra scores 5 out 6, that's performance of 83%, or close to 3000 *performance* rating in *this* match. (performance rating doesn't mean that's Hydra's rating!!). This is not rocket science, but if you still can't comprehend this, I don't think I can help.
