...and as Mike o stated ambient light is everything. We use the ~.8 for
grey since we have lots of rooms with lots of different artists and
ambient light levels. Its a good starting point, final brightness needs
to be tweaked based on room and lighting. Its an interesting
observation to check monitors in the AM and again in the PM with your
eyes first and meter second. If there is any sun light in the room you
will see "eyeball drift" .

In general terms this the sort of range that I think everyone has been
for years. However, this specification does not, and should not, exist
the dark (pun intended). There's a requirement of an appropriately
and calibrated viewing environment to go with the monitor calibration.
can spend US$45K on a monitor and US$20K on the best colorimeter and
the thing up nicely by not ensuring that the viewing enviroment is
SMPTE RP166 is a starting point. As I have been doing a lot of work in
area lately I must say that I am now of the opinion that RP166 is
outdated. The replacement must take into account such things as color
appearance models --some of which is not easy to quantify. Having said
that, RP166 is --by far-- preferable to rooms I've seen, where the work
done in nearly absolute darkness.
