Maybe. I never did it at 130. My 70-200 on a D4 varied from -3 to -13 at medium distances between 200 and 70. On the D800 at medium distance it was +2 and +10 between 200 and 70.
Then I did it at longer distances (maybe 30m) and got +5 and -4 from 200 to 70.

But that is really strange. One way that might happen is if you have focus shift, though that lens is not one I've heard of having it. The 85/1.4 for example shifts focus (I think back) as the aperture closes, so the sharpest focus point at F1.4 moves at F2.8, etc. That's one way this can happen as you fine tune at F2.8, and if it shifts then higher F-stops are softer. But it would take a heck of a shift to cause it to get less sharp at (say) F8, as usually the DOF increase catches up with focus shift in 1-2 stops.
Look at the images it captured -- are they really sharper?
Set up a tripod and forget Focal and do the test yourself and we what happens.
