I am going to attempt to generate my own personal rating and see what I can learn from the process. I believe many of us have a good grasp on the way the USTA calculates these ratings, although few folks really know the ins and outs of the algorithm. Recently I have been impressed with Schmke's contributions … Although he has no inside knowledge, he has spoken at length about how he believe the system works. His observations have rung true to me mathematically. I think that for him the process of calculating ratings for large groups has provided him insight into the process. I am interested in the same thing. I have no intention of calculating ratings for others … rather I am going to publically try and calculate a rating for myself and for people I suspect are very close to the cutoff. I am going to start with public documents provided by the USTA. I have been reading them carefully and they provide quite a bit of detail about the system. Unfortunately, some of these links conflict. I will be using the TLS website for my starting point. While we know they are not spot on, they have been relatively on target this season. The strongest players I have played this season have had the highest TLS ratings and vice versa for the weakest players. While they are not exact, I believe they are close enough to learn something from. Why would I even care? First, I admit there is no good reason to do this. I should just play my matches against whom I am scheduled and do my best. However, it intrigues me and I suspect many of you as well. Second, I am a Physicist so the math/statistics interests me and I have several weeks of free time before the next semester. Third, I just injured my hamstring so I will be out for a few days. This gives me something tennis related to concentrate on while I heal. Fourth, by sharing my observations maybe some of you will point out things I missed or ideas you have. I have found 3 conflicting links on the USTA website, so maybe you have found other links that might shed some light or further confuse me.
