HSV gets the numbers three days in advance, which usually means they're off a little bit by the time the day actually comes.

The information is available to our TSOs on flight sheets that we print out daily - one for the checkpoint (it also includes the rotation, along with an hour-by-hour breakdown of the passenger flow), and five or six for checked baggage spread out amongst the screening locations.

Whether or not the sheet is looked at (and there's no real reason for a TSO to look at one of them in the first place, outside of personal curiosity) is up to the TSO-in-question. I've gone whole days where I never bothered to look at what the flight sheets actually say.
