But of course this is just about what resolution PTGui suggests you as maximum.

In reality calculating a final resolution for a panorama especially from fisheyes can only be an average resolution for the whole image as a fisheye may loose as much as 25% resolution at the corners.

Actually if you take your originals and compare to the final stitched one you will see that the center is much smaller in your panorama.

If you calculate the  resolution from that area you will get 13900 from the D800, Of course this means the areas at the blending point and at the floor and ceiling will be interpolated up to 123%.
