Actually, the three factors are temperature, humidity, and barometric
pressure. Altitude does play a role, but that's already accounted for
in the barometric pressure. If you get the barometric pressure off the
radio or the evening news or something, then yes, I believe you do have
to account for altitude since I think the news media corrects it to
sea level or something.
Anyway, the best way to go is to have a thermometer, humidity
guage, and a barometer with you, and just read the current
conditions. That way you don't have to worry about altitude.
You're right though; an ET by itself really isn't a conclusive
measure of performance. When we give an ET, we probably should
include the environmental data too, or just correct the ET to
standard.
