    Two very interesting points. So when comparing, it's easy to see the tennisrecord numbers. But what USTA number are you comparing to?

    The goal of TennisLeagueAnalytics (TLA) is to very accurately identify the relative strength of players; strength defined as ability to win matches. That's what league players and captains seem to care about the most: "Is Player-A a stronger player than Player-B?", "Is this doubles pair...

    I have no "inside info", and don't need it. I just have the math and software background to model the numbers - it's my field. There are several ratings systems that various other sports organizations use so I started with those. Time consuming, though for me, kind of fun.

    I've read the same thing and you can likely find that info in a USTA sectional FAQ, national changed (or lost) their FAQ when the site updated a few months ago.

    That would be nice but hard to do in practice because you'd have to also calculate the rating with the opponents' singles/doubles separated ratings. The permutations would get out of hand fairly quickly unless simplified and then, well, you might as well just use the all inclusive rating and...

    It seems that rating accuracy is not the goal of the site. The model seems to be a "click bait" model. I've analyzed the numbers fairly well and they don't add up. Just look at the prediction of who should be bumped up and in one district it was wrong 95% of the time. But again, as long a...

    How far can one one achieve in Tennis if he only starts as an adult?

    I know several players who started in their 30's and reached 4.0 and 4.5 in two years, most were fairly good athletes, e.g., college baseball players, accomplished high school sports athletes. I know others who can't get out of 3.5 after many years of lessons.
