Analyzing 2021 USTA NTRP year-end ratings - Bump rates by level and gender

With 2021 year-end ratings published, following on the bump rates by section, next up in the analysis is bump rates by level.

For all these charts, remember what is reported is percentages of players bumped up or down from the listed level, not raw numbers.  So there were not more total 5.5s bumped down than any other bump, rather the percentage of 5.5s bumped down was higher than any other percentage.

Here is the overall chart.


Probably not a big surprise, a lot of 2.5s bumped up, and more 3.0s and 3.5s bumped up than down, but at 4.0 and above, more players are bumped down than up.

Looking at just the women.


Similar trend, the scale of the chart is different because there are fewer 5.5s bumped down for the women.

And the men.


Again, very similar.

It will get more interesting to look at this by section which will come soon.

  1. Thanks for the information. It does make it hard to compare with the different scales. Also not knowing how many people are involved at each level makes it difficult to judge the impact.

    On the whole do you think this round of bumps and dumps will mean women's ratings are getting inflated compared to the men's ratings?
