How to calibrate a Sigma 85/1.4 Art with Sigma dock, different corrections depending on f-stop?!

Standard is to calibrate for the lowest aperture-value (ie 1.4) but I get very different required corrections for different f-stops.

F/1.4 at shortest focusdistance, 85 cm, will give an extremely short DoF so I dont think I will use any wider than f2.

Should I calibrate for f2?

Is it normal to get different correctionsvalues for f-stops that close?

Why is it standard procedure to calibrate att widest aperture?

Anyone....
