OK I tried it... and not great.
It's nice that you only have 4 points and gets way better results than Windows 16 point calibration, but the end results are:
-> I still needed to make the offset trick required to do when using any calibration method using Windows calibration tool
-> I can't reach ~10px from the right.
-> Corner precision is better than any calibration method available
-> side area of the screen still have an offset from the center
Personally, I had much better results with my 80 point calibration in Surface Tweak Tool. But of course it doesn't work, currently, with Wacom drivers, something that I need to work on.
