Wasn't the Winter Cup at the end of February the same? It was paired with Nastia Cup, which is usually the same as American Cup. I just figured they changed the name again
Winter Cup is a different meet. American cup did not happen last year due to covid, and I think it was taken off the world cup circuit so they aren't having it.
Winter Cup and Elite Team Cup have been going on for a while. They just added women to it last year.
