I think the decision should depend on the consequences instead.
The consequence of a longer wait is just that.
You have a few seconds wasted, if link detection does not work properly on
your hardware.
The consequence of a not long enough wait, is that Debian will simply fail to
install over the network.
I think the wait time may be longer on the newer generation of power efficient
switches that power off ports that are not in use.
Takes 3 full seconds here in practice (HP 2410G rackmount switch).
