Usually not but nothing is ever set in stone. Especially with giving MOCs time to call... they could call anytime. The system I think is set up to automatically update the portal after they allow the MOC so many days to call (not sure on official number).
I've never seen USNA update the BGIS (BGO) portal on a WE as it's not a working day at USNA. Don't say it can't ever happen -- just not seen it. I would expect the same to be true of the CIS (candidate) portal. So, sleep easy this WE!
