Anyone else have any other explanations?
Figure two of this reasearch paper contains a lift-curve slope of roughly the shape you are describing:

If you concentrate on the "steady" (solid) line you'll see a small recovery in lift with alpha when increasing past 30 degrees. I can't see it stated anywhere what the actual aerofoil or model was, though.
