2016 USTA League NTRP rating bump percentages by section for the 4.5 level - Interesting tennis league stats

I've looked at the bump up/down percentages for the 3.0 and 3.5 levels.  Now the 4.5 levels.

Here are the percentages of bumps up and down from 2015 for the 4.5 women.

Among a bunch of sections that had 2-4 times as many players bumped down than up, Caribbean somehow ended up with nearly 10% of their 4.5s bumped up.  Southwest went way the other way with over 15% of their 4.5 women bumped down.

And then the same for the 4.5 men.

The thing that jumps out here is that Hawaii had a remarkable number of bump downs for players that were at the 4.5 level.  Most other sections had more bump downs than up, but at over 17% Hawaii led the way.

Interestingly, Northern and Eastern are the only sections that had more bumps up than down.
