I'd think not as it's actual employees that verify what you've entered against your transcripts, and people usually don't work weekends. Then once everything matches up, the system will calculate GPAs and that shouldn't take long and can probably happen over the weekend...It'll happen soon don't worry, you're still early.
I don't think so. I think schools just get an update, which is added to your file. Your application might've not even been looked at yet (they send that email to everyone, and they don't have enough employees to view each one at the same time, right?! It's just so you know that your file is complete). But even if it does affect/delay anything, I'd say the "line" isn't very long cause it's still really early in the cycle.
