reikan focal pro lens calibration unboxing

It currently supports over 40 cameras and claims to be the only automatic autofocus calibration solution for DSLRs. Focal has been around for 10 years, having been first released in 2011. FoCal Pro has the following extra information available during calibration, Historic Results, Focus Consistency, Astigmatism Factor, Result Convergence and Image Motion. The updated version practically rewrites code for the software. FoCal Plus inherits the Lens Profile graph display from Focal Pro to make it easier for users to understand what’s happening during the calibration process. The Pro version offers a much more comprehensive analysis of your camera and lens combo’s performance, including telling you what your sharpest aperture setting is, testing all of your focus points and comparisons with all of Reikan’s other users, so that you can see how your lens is performing relative to the community. What I was wondering about is I've read that doubling the results and entering those values to the dock settings is needed and some mention it's not needed. Reikan has just released version 2.9 of its autofocus calibration software, FoCal.

These results have surprised me as I could have saved myself £69.95 LOL! I have tried Reikan FoCal and the Dot Tune and the results are the same or very close to each other, I had to switch to the Dot Tune method for infinity though. The type of photography is fast jet aviation, shots are handheld. Sigma 150-600 C, usually zoomed in from 500mm to 600mm with the focus switched to AF, set to 10m-infinity, OS switched off and Custom switched off. Nikon D500, usual setup in manual with the shutter speed from 1250th upwards, ISO set to Auto, f8 to f10 Reikan FoCal pro suggested f10 to be the best aperture for this lens.

I was experiencing soft images hence the need for calibration.
