The database is downloaded from RR into Uniden servers on Sunday nights (IIRC) and made ready for Sentinel on Monday mornings (Central time).
I'm in the Mountain time zone and generally find it to be ready around 0900, so for you in NYC it'd be 1100 Mondays.
If the DB admin assigned to your submission has worked the data prior to let's say 6pm Sunday, I'd think it would be in for the next morning, otherwise it would be the following Monday.
