This is a typical case where the figure of merit (here: slope error) is dominated by the local, quasi-static response (here: bump) which would be grossly underestimated when not including static correction. I also show that the brute-force approach (including hundreds of modes) would very slowly converge to a &#8230; very inaccurate value.
