For the averaging, you need to detect some experimental signal over some time window. The stronger that signal, the less time you have to average for to get the same uncertainty. So: is a superradiant atom-only source as described in the paper as 'bright' as atoms coupled to an external resonant cavity? I'm no expert, only curious what the trade-off is. You mentioned the difficulty of getting enough power with an acceptable S/N; my question's along the same lines.
