Was this about building FXN and MBD? Or better said: the packing of the helices
of these proteins. If so: He made several modells given the EXACT secondary
structure (100%) and he made several modells differing quite a lot from
the native folding.

I cannot agree, Chou and Fassmann also result in about 60 to 65%. And by the
way, random "prediction" results in 50%. So 65% is a VERY little but not a lot.
