2017 USTA League Year-End Rating Analysis - 4.5 Bump Up/Down Percentages - Interesting Tennis League Stats

I already wrote about the 2017 year-end bump up/down percentages and also by gender, and started looking at levels with the 4.0 men and women,  and 3.5 men and women, now the 4.5 men and women.

First, the 4.5 women by section.

We see that every section, other than Caribbean, had more players bumped down than up, and by a wide margin.  Southwest had over 15% bumped down and less than 4% bumped up.  A few sections like Missouri Valley, Pacific Northwest, Florida, and Eastern were pretty stagnant with under 7% bumped up or down.

And then the 4.5 men by section.

Here, Eastern is the one section with more bumps up than down, but just barely.  Every other section had more bumps down, many by a significant margin.  Hawaii stands out with over 17% of their 4.5s bumped down!  Look out for Hawaii at 4.0 Nationals next year!

What do you think?  What does this mean for 4.5 play in your section in 2018?
