What NTRP rating combination works best in USTA League 40 & over Mixed? More Interesting Tennis League Stats

I looked at what ratings combinations work best for 18 & over Mixed yesterday, so naturally it makes sense to see the same info for 40 & over.

Again, this is looking at tens of thousands of matches in the 40 & over division of Mixed played over the last few years.

Here is how it looks for 7.0:
  • 4.0/3.0 vs 3.5/3.5 - 4.0/3.0 win 60% of the time
  • 3.0/4.0 vs 3.5/3.5 - 3.0/4.0 win 52% of the time
  • 4.0/3.0 vs 3.0/4.0 - 4.0/3.0 win 58% of the time

And for 8.0:
  • 4.5/3.5 vs 4.0/4.0 - 4.5/3.5 win 61% of the time
  • 3.5/4.5 vs 4.0/4.0 - 3.5/4.5 win 54% of the time
  • 4.5/3.5 vs 3.5/4.5 - 4.5/3.5 win 57% of the time

Last, for 9.0:
  • 5.0/4.0 vs 4.5/4.5 - 5.0/4.0 win 62% of the time
  • 4.0/5.0 vs 4.5/4.5 - 4.5/4.5 win 53% of the time
  • 5.0/4.0 vs 4.0/5.0 - 5.0/4.0 win 57% of the time

This looks similar to the 18 & over but finally for 9.0 the 4.5/4.5 comes out ahead in one scenario.

So, it appears you want those unbalanced team!

    I don't understand this. Let's take 7.0 for example. There should be 6 scenarios, not 3. I guess this would be the same for all. 4.0 guy/3.0 lady vs 4.0 guy/3.0 lady, 4.0 guy/3.0 lady vs. 3.5 guy/3.5 lady, 4.0 guy/3.0 lady vs. 3.0 guy/ 4.0 lady, 3.5 guy/3.5 lady vs 3.5 guy/3.5 lady, 3.5 guy/3.5 lady vs 3.0 guy/4.0 lady, 3.0 guy/4.0 lady vs. 3.0 guy/4.0 lady.

      Stats only apply for when there are different rating match-ups. If you have a 4.0 guy/3.0 lady vs. 4.0 guy/3.0 lady, a 4.0 guy and 3.0 lady team will win....100% of the time! :)

      Correct, match-ups of the same pairs will always be 50%, so no point in showing those.
