USTA League Nationals Week 7 Semi-finalists - What tie-breakers had to be used?

Despite some rain, delays, and short-format on Friday, the round-robin phase of week 7 of USTA Nationals is complete and we have four sets of semi-finalists in Orlando.

The 6.0 level had three undefeated teams in PNW, Mid-Atlantic, and Intermountain, and remarkably there was only one 3-1 team, New England, so they advanced.  We were very close to a 2-2 team advancing to the semis!

The 7.0 level had three undefeated teams in Texas, Southern, and Mid-Atlantic, and then there was a 3-way tie at 3-1 for the last spot with with SoCal getting it on best court record 9-3 to Intermountain and NorCal's 8-4.

The 8.0 level had three undefeated teams in SoCal, Florida, and Middle States, and then had a 5-way tie for the last spot at 3-1.  Mid-Atlantic and Texas were tied at 9-3 on courts ahead of Eastern, PNW, and MoValley, and Mid-Atlantic got the spot having lost one fewer set.  They did win the same number of sets so using the better sets won percentage would have resulted in the same team advancing, but it is interesting that had they tied on sets lost, Texas would have easily won the games lost tie-breaker having lost 14 fewer games.

The 9.0 level had two undefeated teams in Southern and Mid-Atlantic, and then a 4-way tie at 3-1 with MoValley and Florida having better court records than NorCal and PNW.

These teams will play for the last titles of 2019 tomorrow!
