For my thesis (many years ago) I did something similar with the Corning
Code (Abinit's precursor). I found the results were sensitive to the
fitting polynomial. Have you tried anything other than a quadratic?

(about effective masses) I would agree a second order polynomial may be poor in some instances. I did something too a while ago (PRB 46, 2086 (92)) with a fourth order polynomial and it seemed fairly stable.
