Now, here is a feature request which will probably be rejected but I post it nevertheless.
During long VarAC QSOs we get a good amount of SNR graph data. We can see how a band changes over time in terms of propagation and detect QSB patterns, etc. Sometimes we also clearly see the effect of local radio noise differences. After all, SNR means Signal to Noise Ratio or more precisely:
SNR/dB = 20 x log10 (V_signal / V_noise) (both voltages are across the same impedance)
During shorter QSOs however, the graphs often look like this:
Not very meaningful at all because there are just not enough points. We can't always have longer chats - that is understood.
Now here is my request: I would like to keep a connection going over 30 minutes or thereabouts for the sake of collecting SNR data. Of course this would only apply and be limited to QSO frequency slots (not on a calling frequency). The distant station can be "AWAY", so only one operator is needed. I know it may be a somewhat esoteric request but then we have for example hamsci.org which is dedicated to the science aspect of our wonderful hobby.
Any suggestions, comments, critiques are most welcome.

SNR Verbose mode is out in V6 which provide a solution to your ask.

Why would you have to reinvent the wheel with so little data available? I assume that given your background working with a lot of data will not be a problem, so go to the PSK reporter website and there you can request data for 24 hours or the whole week.Do that with calls from different continents and you have masses of data to work with. Since it is a static link, it can even be automated and downloaded as an ADIF file. https://pskreporter.info/cgi-bin/pskdata.pl?adif=1&days=7&senderCallsign=nc3z
Whilst VarAC logs the SNR from the conversation (and by requesting it from the VARA-modem?), the main party to 'blame' here is the VARA-HF modem. It should log or indicate the SNR of each received transmission to create a reliable dataset to analyze the conditions over the whole connection period, but now it only displays it in the UI and logs the average SNR of a connection. I'd put in a feature request to optionally report SNR every time VARA-HF sends traffic to VarAC or other connected apps. 73,

Unfortunately only us more technical hams would appreciate this. But to your point, during our daily 10M QSO (which last 20-30 minutes) I trigger a SNRR very frequently to fill in the graph better. Maybe a "verbose" mode that can be turned on during a QSO to fire off more data points?
Or another cool thought, what if like a LHR you could query another station for your beacon SNR over the past XX hours?
Here is todays' 10M QSO where I fired off a SNRR as much as possible.
