(1) To address jma's comment above... I will state - emphatically - that there is no "weighting" of results at Tennis Recruiting. Every week, we take all results for a gender and pass them to our ranking system, and our system produces a single objective ranking from those results. There is no weighting - a win is a win. And every Monday, we throw out the previous week's rankings and start fresh with a new 52-week set of data.

(2) As a more general comment, no ranking system can get everything right., and most ranking systems do a better job with players who have long records. We like to think that our system does a good job of being predictive based on past results. Our system also employs a time decay factor so that recent play counts more than play from a year ago - to take into account that players improve/decline over the course of a year.

Best,
Dallas
No system is perfect. But Tennisrecruiting.net is the best system out there.

I am wondering if we can pay a fee to TRN for you to tell us what my son's ranking might have been if he were a sophomore. It can be done pretty easily, first find him in the master ranking list; then find the sophomore who is ranked just ahead of him. This virtual ranking may be interesting in our conversation with college coaches. My son beat several 5 star sophomores in the past 12 months and he would likely be a 5 star if he were a sophomore.
