You cannot know for certain. If the xrun is Ardour not delivering
audio to the sound card then you get a click in the output audio. Not
a killer problem. If the xrun is Ardour not acquiring audio from the
sound card then the data is lost forever. Much bigger problem.

I would recommend that you record with latencies just high enough to
not be overly painful, and then push them higher when doing mixing if
you are not interfacing with external signal paths for post
processing.
