Hi, James. This occurrence is normal when you use polynomials for fitting. The simplest is to generate more points in the region of interest, i.e., use a finer sampling. Or, if you know the exact function describing this "peak", you can fit it - FitFunction[], or use FunctionInterpolation[]. Still, you can choose among different types of polynomials Method -> "Spline"/Method -> "Hermite", ... but these are still polynomials. -jb-
