The pitot style bench isn’t comparing to anything, it’s trying gauge what the actual flow of the air is through the flow tube.
And, in order to know what the flow is...... you need to know what the air density is.
So, the weather matters.
...and it does matter! I have a redundant system of verifying Baro and Humidity, and I have to keep tabs on conditions as I go.
Selling that 110 probably felt pretty good, huh. What a pain to use!
gotta warm it up all the time... like an ex I used to have..
