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.
We now enter the third weekend of Nationals, and the 40 & Over 3.5 level is being played in Oklahoma City. Here is what is likely to happen for the 3.5 women.
As a reminder, my simulations are done using my Estimated Dynamic NTRP Ratings and looking at the average rating for the top group of players on each team, the actual schedule each team will play, and then doing a million simulations of the matches with some random variation in each team's expected result.
Teams: 17
5+ undefeated: <1%
4 undefeated: 3%
Tie for 4th: 91%
Size of tie: 4 - 26%, 5 - 25%, 3 - 17%, in theory could be 13!
Sets tie-breaker: 31%, 2 teams 61%, 3 teams 31%
Easiest schedule: 3.50
Toughest schedule: 3.58
Likely semi-finalists: Florida, Middle States, NorCal, Intermountain
Contenders: Caribbean, Texas, SoCal, and Eastern
It should take a 3-1 record to make the semis, and the simulation says a 7-way tie for the top-7 spots at 3-1 is a real possibility.
For those interested, I offer a variety of reports to make Nationals more fun and help captains prepare. I have a Simulation Report that has all of the details of the simulation including the average ratings for each team, each team's schedule strength, the most likely record for each team, and the chance of each possible record for each team. I also offer reports to help teams scout opponents in more detail, both a Flight Report with full roster averages, top-8 averages and played by court averages for each team, as well as full Team Reports with detailed ratings for each rostered player and stats who who plays with who and on which court and how they do together. Contact me if interested in any of these reports.
