Pyra stylus calibration not working ?

[PowerGod]

I tried different times the calibration utility for the stylus, but I can't see any difference ... the pointer is always different pixels away from the touched point.
Worked the same on Buster and also on Bookworm (now 12.15).

When I click in the middle of the screen seems somehow correct, but the more I move to the borders it become less and less precise ...

Am I the only one with this issue ?
Do I have to do some manual configuration after or before the calibration ?

I am aware of the hardware limits at the sides, but I can't even get it precise on the rest of the display.

Was this already discussed somewhere ?

Thanks.

EDIT:

Also it speaks about a "get_precalib.sh" but I can't find it on the system.

EDIT:

Also I noted that in some points, when I keep pressed the stylus without moving it, the pointer keeps trembling doing random micro selection squares or grabbing icons.

I was always under the impression it was my bad fine motor skills trying to hit an exact point during calibration, so blaming myself for not doing it right (which might be true).
But, I never purposefully tried to do it incorrect to see the result to see if the calibration itself was working properly.

I actually tried, but it's pretty difficult since the utility resets every time it detects wrong coordinates ... so I started to click constantly at random in circle and at some point the utility got the values, absolutely different from the ones I got when I was precise.

Anyway nothing changed ... I'm not sure if that xorg configuration is really used to set the coordinates ...
