You don't know. You just decide that it's maximum tolerable for
you/your setup/hardware/connection/preferences/whatever, otherwise you
are 99.(9)% sure that something is wrong somewhere with your system, but
you don't give up your Emacs instance for that and rather get indicated
that there might be a potential problem.
P.S. How did people know that 2 hours would be enough for TCP keepalive?
