WSUS - Expected behavior during the scheduled installation

I am preparing to patch multiple 2012R2 servers in mulitple offline networks that haven't been patched in over 2 years, so trying to get an understanding of the expected behavior during the installation process. If I use the settings I have defined below, will the servers just keep downloading and installing updates until they are fully patched or is there an interval that starts when you schedule the maintenance and stops after a certain period of time? Let's say there are 200 patches needed on Server A, they have all been approved in WSUS, and I schedule the installation as defined below... will Server A keep downloading and installing even if it takes until Sunday?

Use option #4 – Auto download and schedule the install
Deselect “Install during automatic maintenance”
Set “6 – Every Friday” for the scheduled install day
Set “17:00” for the scheduled install time

You will have to run more than one round for sure, so only scheduling for Friday adds a lot of delay.
Each go will download all updates which are detected as applicable at that time. Some updates are applicable only after other updates are installed.

Correct, on friday, you should select every day instead of every friday so that it will install anything over the weekend even if a reboot (or two) are needed. Then undo that setting on monday.

I would however recommend a scripted solution for this, see my article: https://www.experts-exchange.com/articles/6852/Automatically-updating-a-new-windows-installation-scripted.html (this applies to all windows versions)
