Simulating 2024 USTA League Nationals - 18 & Over 7.0 Mixed

USTA League Nationals for 2024 continues this weekend!  The schedule is more compressed this year, normally Nationals would have started in early October, but this year we started later and have more events each weekend.

This weekend has seven events, 18 & Over 7.0 and 9.0 Mixed in Orlando, 18 & Over 6.0, 8.0, and 10.0 Mixed in Surprise, and 55 & Over 7.0 and 9.0 in Scottsdale.

I've been doing simulations since 2018 and have found that the four semi-finalists are usually in the top six to seven projected teams, and more often than you might think, I project the four semi-finalists perfectly.  There are surprises sometimes and a mid-pack team overachieves and advances, that is why the matches are played on the courts and not on a computer.  Still, it is interesting to do these simulations and see how the projections do.

Why do these simulations you ask?  The primary reason is that the format for USTA League Nationals is now a flight-less random round-robin where each team plays four other random opponents.  This introduces significant variations in schedule strength, the possibility of an undefeated team not making the top-4, and teams vying for the top-4 perhaps not having played head-to-head and unfortunate tie-breakers being used.  The simulations aim to educate folks on how it all works and look at what may happen.  Also see this write-up for some things to know about Nationals.

Because of the more compressed schedule, I likely won't have the time to do previews/simulations of all events, but will try to do a few.  Let me know which you'd like to see!

Like I did last year, I'll be primarily just giving the data from the simulation and not writing a bunch of words.  Most of it is self-explanatory, but the favorites and contenders will be listed in alphabetical order.  The strengths are based on played averages in playoffs.  Contact me if you want to learn more.

On to the projections from the simulation, next, the 18 & Over 7.0 Mixed.

Teams: 16 (NorCal missing)
Chance of 4 undefeated: <1%
Chance of 5 undefeated: <1%
Chance of tie for last spot / most likely size: 82% / 4
Strongest / weakest team strength: 3.62 / 3.37
Toughest / easiest schedule: 3.53 / 3.45
Favorites: Hawaii, Middle States, SoCal
Contenders: Caribbean, Eastern, Florida, Mid-Atlantic, Midwest, Southwest, Texas

Again, a very competitive event it appears with a very low chance of a lot of 4-0 teams, just one projected to have that record.  But it will likely still take a 3-1 record to make the semis, but there are a lot of contenders vying for it.

What do you think?
