Sure, it depends on the scale. My spreadsheet is set up with the variable "Fork", representing A-4, to which I can assign any pitch - say, 435, 440, 442, etc. Unison pitches are figured from the "Fork" with =0.0625*fork*2^((Unison-1)/12), and tensions from the pitches, etc. I can look at the total tension sum, change the fork, and subtract. Different scales will give different numbers. No, it's not all that accurate, because the tuning stretch and resulting increase in tensions isn't figured in, but it's plenty close enough for scaling. >Not enough to be concerned about, IMO, seeing as how most plates are >WAAAAYYY over engineered.
