A renaissance lute is often smaller, so a high A frequency results in very thin strings, which becomes a problem if you start using gut . My renaissance lute is 63.5 cm. I had it first with fluor carbon and needed 0.38 mm for the chanterelle at a=440. In a calculation with your script I get 0.40 mm for the carbon and 0.45 for gut at a tension of 8.50 kg (???) at a=440. A tension should be approx. below 40 N, in my opinion to get some useful string diameter. I garantee that the 0.45 mm gut will break at such a huge force.
In my own calculations I use a=415 and get g' ~ 0.40 mm for a plain gut string, and I know this works. So, the script gives strange values. Compare it with arto's strings calculator, which is correct. I can also send you a python script which I have used for some of my calculations. I agree with a increasing tension for higher strings but take only the 3 highest strings. Normally I start with 37N (yes, newton, not kg because it's a force, not mass and it's also not kg/m) and decrease it to 33N for the second and 27N for other strings. This is a little bit low tension, but a good start. I use it on theorbo and archlute too which creates the ability to play at 440Hz too at higher tension.
