New features to Estimated Dynamic NTRP Rating Reports - Better insight into your rating

With Sectionals wrapping up and the start of Nationals less than a month away, now is the time many players are done for the year and thinking about how they did this year and how their rating has changed.  Have they improved?  Might they be bumped up?  Or did they have a tough year and are worried about being bumped down?

My Estimated Dynamic NTRP Rating Reports have always provided great insight into where your dynamic rating likely is and provide a very accurate estimate of what your year-end level will be.  But more than just seeing a number, my reports always include my written analysis and comments about your rating and how it has been affected by play in different matches.

To aid in that analysis, I've just added some additional features to the reports.

First is around win/loss records.  I've always broken out records by singles vs doubles, but many players play in different divisions, or may play up and play at different levels.  To show finer grained detail about how you've done in each different situation, I've added win/loss records by division and level.

Here is an example, the new features in bold:

Match Record: 18-6
Singles Record: 1-0
Doubles Record: 17-6
Adult 18&Over Match Record: 6-2
Adult 40&Over Match Record: 8-2
Adult Other Match Record: 4-2
3.5 Match Record: 16-6
4.0 Match Record: 2-0

This summary will clearly show if you are doing better/worse in any particular league or level and help you identify what is working or where you need to improve.

But while team wins and standings are (in most cases) based on court wins and losses, what really affects your rating is the score and ratings of your partner (if doubles) and opponent(s).  I've broken out average match ratings a bunch of different ways, from singles vs doubles, including at different levels, and recently added showing averages for opponent's level and rating at the time of the match.  I just added showing averages for your partner's level and rating as well.

Here is that whole section with the new(er) items bolded.

Singles Average Match Rating: 3.46
Doubles Average Match Rating: 3.46
Singles Average Match Rating by Level:
3.5 - 3.46
Doubles Average Match Rating by Level:
3.5 - 3.44
4.0 - 3.67
Average Match Rating by Division:
Adult 18&Over - 3.49
Adult 40&Over - 3.55
Adult Other - 3.27
Average Opponent NTRP Level: 3.52
Average Opponent Dynamic Rating: 3.32
Average Partner NTRP Level: 3.52
Average Partner Dynamic Rating: 3.42

This shows you what is really affecting your rating, up or down.  Are you better in singles or doubles, and does that change based on the level you play?  Did you do better/worse in a given division?  And how much of your rating being high or low is due to the level/rating of your partner and opponents?  These stats can clearly show you all that, and I'll always add commentary explaining it and answer any questions.

Last, for players that went to playoffs, you want to know how you did in those matches compared to the rest.  These are matches where you get to test yourself against (usually) other strong players from other areas, districts, or sections.  These matches also have an added impact on your year-end rating and thus the NTRP level you will end up at.  The chart included in a report has always denoted these matches so you can see how they compare, and I've always and will continue to comment on the effect they will have at year-end, but now I've added showing your average match rating in playoffs.  But even if you didn't play in playoffs, you may have played players that did, so I am also now showing your average match rating in your regular season matches against them.

Here is that section from the report.

Average Playoff Match Rating: 3.97
Average Match Rating / Matches vs Playoff Players: 4.00 / 3

All of these new features are now shown in the example individual report.

Ultimately, folks are often interested in if they will be bumped up or down, and that in part depends on the year-end calculations.  And while I don't do my full year-end calculations until, well, year-end, these additional stats and metrics will go a long way to explaining what is likely to happen and why a rating is where it is.

Should you be interested in getting a report, contact me at ratings@teravation.net.  All these new features are now included in reports with no pricing changes, and if you already got your report for the year and just want the new features, drop me a note.
