Thanks Gebhardt,

Analysing and comparing figures for x-tol and tri-x roll film for example, there is no linear/constant relation between the two lists.

for trix-x 6049 its going from 1.34 over 1.29 to 1.36
for tri-x 6043 it's going from 1.35 to 1.17

So wondering which formulas are applied?

And wether these formulas counts for every combo film-developer?
