The USTA is about as non-standardized of a large organization that I have ever encountered.
Standardization would make the USTA a better organization IMO.
What if one area played all matches with 8 game pro sets or banned self-rated players from playoffs? What is one area counts singles ratings to your NTRP and another doesn't?
The fact that the USTA fails to have the same rules across the country is embarrassing IMO. I am glad my profession doesn't operate like the USTA.
