For anyone who wants it, I have a excel sheet that uses TTB table 1 to find the true proof.

This is a link to the excel spreadsheet that I made. I used ocr software to put the TTB table 1 in the second sheet. This should be officially sanctioned by the TTB. I simply call the values closest to the input values from the table and then interpolate them.
I am a student at UC Davis and my professor and I made an excel sheet that uses the TTB table 1 in order to change the apparent proof to True proof at 60F. I was wondering if anyone could give me suggestions regarding if the calculator is helpful and if it always works.
I cannot upload excel files though.
