Hello Hans-Peter,
you're right: The algorithm assumes that the first -3dB point it finds is
the -3dB point of the filter. I'm not certain what's a good and generic way
to avoid this to allow filters to have that much ripple?
Suggestions?

Your filter has too much ripple to be useful. Please don't ask me to analyse such rubbish!
