Please reattach your leg, Jim just pulled it.

A quick google effort did not find significant results for humidity with CO2
and covid, except that better CO2 sensor might already use humidity measurement
to compensate for CO2 measurement issues based on humidity. But nothing relating to
Covid.

If i remember correctly, Covid sits on droplets. Those are not really humidity.
As soon as they dissolve and turn into humidity, the covid (an other viruses)
attached to them become inert AFAIK. Of course, the higher the humidity and the lower
the temperature, the longer this disolving might take, but whether or not the rate of 
dispersion as guessed by those factors is relevantly different from what can already
be gauged by CO2 alone is not clear to me. The absence of more google results could
indicate that no one managed to create significant improvements in predictions
using these factors, no ??

I hope we (or at least the NOC) are not as clueless in reasoning about the
causes or mitigations of WiFi issues, as we are about Covid. Which is
not a criticism about the measures we're taking. Its more a recognition,
that we can't be any less careful with the little we really know. And having
to be more careful (mask up) in tiny rooms seemed logical to me, but this
experiment i think was a nice re-confirmation of that (IMHO).
