I looked at https://atlas.torproject.org/#details/D60B02A13F5D9CAFD6EC27A5332C5FEF5B769105
/ 4FreeSpeech for the latest vote:

moria:  w Bandwidth=3012 Measured=1890
maatuska: w Bandwidth=3012 Measured=3820
gabelmoo: w Bandwidth=3012
longclaw: w Bandwidth=3012

consensus: w Bandwidth=20 Unmeasured=1

Once you get 3 measurements you should pop over to a real measurement.
(How sane it stays is a whole other issue.)

It's possible (although not simplified) to grab historical
measurements from archived votes and consensuses and figure out how
and when different dirauths voted on you.
