Yes, I agree that it would be good to note photometric nights. I think eventually this can end up in the software, but to start we should just record it here in The Asterisk* Science forum. We just don't have the people power to keep updating the software every few minutes.
I think doing automated differential photometry for a whole year on all the CONCAMs is a great idea but not practical before the January AAS meeting. Also what star is visible for all the CONCAMs all year round? We would have to pick and choose different stars. Again, in my view doable in the long run but time consuming and impractical in the short run. Also, I have found that it helps to do a project preliminarily visually first to get a feel for the difficult parts. This, in turn, helps write the code for the automated analysis.
Next, I looked at the MK movie file for the non-photometric night of Oct 16. Here it is:

There are clouds coming in and out much of the night, but there do appear to be some clear times in the middle of the night so it is surprising to me that even these are not photometric.
Next, it seem many times when I play a movie like this, interesting things come out. Here are two cool frames that involve either satellites or meteors. I think I see at least the first one on Haleakala's CONCAM so we should be able to tell the height from parallax between the two stations. The height should tell us if it is a meteor.

The jagged edge does not appear on the FITS frame. If this is a meteor it is perhaps the second most impressive one seen by NSL, the first being our logo earth-grazer seen during the 2001 Leonids.
A few minutes later here is another flash just under Polaris:
