It looks like it does fix the problem with the power.
I have modified interpol.mac, but for my purpose it's terribly slow.

I killed my program after 20 minutes,
because doing it by my own I need only about 2 minutes

I usually vary the degree parameter for ratinterpol.
and select the nicest factored formula, which works for me.
