Sample calculation example (p 32), we have carbon/nitrogen ratio:

$$\large {c \over n} = \frac{b_c\,+\,a_c S}{b_n\,+\,a_n S} = \frac{33.6\%\,+\,(50.4\%)S}{5.6\%\, + \,(0.09\%)S}$$ ﻿ ﻿ ﻿ ﻿ , S = weight ratio A/B

The article says c/n = 30, S = 0.805, which is way off.
Try above formula, for S = 0.805, we only get c/n ≈ 13.08

Correct value for c/n = 30 should be S ≈ 2.818

I have not read actual code, but if its own example is wrong ...
