I checked in today at a LC property and the front desk agent put "VIP 4" with a pencil on the check in document. Few weeks ago I was staying at a different property (Sheraton) and when my room was being cleaned I took a quick look at the housekeeping report laying on the cart and next to my room number there was "VIP 7", also another room had note "VIP 8" - for all other rooms the column was empty.

Does anyone know what those statuses mean? Both hotels were legacy SPG, so I don't know if this system applies at Marriotts too, it also seems to be property specific (unless I somehow advanced/lost 3 levels) over the last 2 months? I tried searching but could not come up with anything.
