Yeah, I've given up on the USTA and ITA sites and I've been going directly to the host schools' sites from the beginning. USTA has got to have the most unorganized, difficult cornmaze website I have ever seen.
The host schools have control. If they choose to post them on multiple sites, they can coordinate that. It's redundant work so I assume they just keep one accurate draw in a format they are familiar with and the other sites just pick up the results after the fact.
