Default Compressible Mass Flow Spreadsheet

how useful would this be? i have something like this and im pretty sure its correct however i dont know how useful it really is especially with the limited cam specification inputs.

thoughts on this?

the way it works is that it uses specs at .050 lift and converts it to actual time the valve is open in ms and also calculates speed of sound based off of IAT. on top of that is the intake runner (head included) cross sectional area to the back of the valve.

what it will spit out is 1) speed of the air flow at any given RPM (set up to work through the range) and 2) how much the air compresses on the back of the valve.
