DF has shown it well. IC, note that in that table, you are talking about 3 films in 4 different developers and the fact that they may have the same coefficients is merely coincidence. So, in that table, Royal X pan in Polydol behaves like Super XX in HC110 B. In DK-50, these two films are a 34 and a 36 which would be quite far apart. And as the above charts show, behavior is non-linear.
