agreed tennismonkey, the USTA has got mixed all jacked up with the levels
mixed with the women .5 higher than the men, would look regular doubles.
4.0 guy / 3.0 lady vastly different than 4.0 guy / 3.5 guy in 7.5 Combo or even 8.0 mixed with 4.0 / 4.0
7.5 combo Doubles completely different game than 7.0 Mixed
If it was 7.5 Mixed with a 4.0 lady, it would have been more fun for sure.
