Sharpening could have a different impact due to the different AA characteristic.

But sharpening is typically not affected by RAW profiles (you wrote "The center resolution characteristic may be different due to the different RAW profile of the cameras").
Surely, for instance Adobe, caters to camera / lens manufacturers by doing some "under the hood" processing, but to the best of my knowledge, sharpening levels for the K10D/K-5 are not specified by RAW profiles.
When you introduced the K-5 for lens measurements, did you attempt to calibrate the sharpening level for the K-5 so that MTF results should be close to K10D results (whenever the K10D isn't outresolved)? That would make sense, if the absolute measurement figures were to make sense.
P.S.: It would be great to be hearing from you regarding the odd peak performance shift of the FA 31/1.8.
