Estimated Dynamic NTRP summary reports available for the Pacific Northwest

Those of you that follow my blog and estimated DNTRP ratings may have wondered why I announced summary reports for the Denver Metro Area but not the Pacific Northwest given that it is the PNW where I started doing the ratings.  There was no slight intended and in fact I can generate summary reports for the PNW for those that are interested.

An example report is shown below and will include results from regular season matches played in Men's and Women's Adult, Senior, Super Senior, Super Duper Senior, and One Doubles leagues for the 2012 league season.  It won't include Mixed league results, as those are not used for computing year end ratings unless you are a mixed-exclusive player.  But contact me if you are interested in a report on Mixed.

Current NTRP: 4.5
Estimated DNTRP: 4.47
Match Record: 12-2
Sets Won-Lost: 24-5
Games Won-Lost: 155-72
Best Match Result: 4.92 on 2012-08-25
Worst Match Result: 3.80 on 2012-06-26
Highest Estimated DNTRP: 4.55 on 2012-09-19
Lowest Estimated DNTRP: 4.28 on 2012-06-26

This chart shows both how the Estimated DNTRP changes with each match, and the specific rating computed for an individual match.  This gives a nice visual view of how each match is rated and the trends in your rating.

If you are interested in purchasing a report for a small fee, please contact me.  And if you aren't in the PNW section or the Denver area but are interested, let me know and I'll see what I can do.

  1. Your summary is fascinating. What is your fee? Today I was looking more closely at the PNW Early Start Ratings and comparing them to your ratings. I am a 4.0, with a 3.92 women's rating; and, I noticed that several (I stopped at 10) with ratings below mine, ended up with 4.5 Early Start Ratings. I know there's a lot that goes into the ratings. But, still. Also, since teams at USTA 4.5, can now have two 5.0s play on your team, the impetus to have a 4.5 rating is not as high!

    Anyway, I was just wondering how the women's ratings in that particular range could be so far off, since your statistics are virtually spot on!

  2. @Anonymous, thanks for the comment.

    A few things can contribute to differences. One is that the early start ratings do not include matches from the One Doubles league but the ratings I posted do. The other is that early start include matches from local playoffs which were not included in what I posted.

    But e-mail me at computerratings@techrunning.com with your name and the names of the players you checked and I can look into it more as well as let you know how I can get you a report for yourself.

    Thanks!

    1. I did some analysis of those on the early start list bumped to 4.5 and my estimated ratings predicted 84% of the bump ups. See http://computerratings.blogspot.com/2012/10/how-accurate-are-estimated-dynamic-ntrp.html

    2. Dear Mr. Schmidt:

      Wow. Thank you so very much for already checking into this. The reality is that I'm right where I should be--a 4.0 on the cusp, who does well at my own level, and can compete up @ 4.5 with mixed results. I think my rating should be 4.0. That new rule of letting two 5.0s players play on 4.5 teams (even though they have to play in the #1 spot), is really going to make for some interesting results. Thanks again for helping all of those in USTA have a better understanding of the ratings. It's too bad that USTA makes such a mystery of it all. But, we're sure fortunate that you're out there somewhere helping us keep our "tennis egos" in check! Cheers.
