Input shaper values - FW 6.5.3

I just updated to the final version of 6.5.3 (from the RC release).

Default values for input shaper are X - MZV 60 hz and Y - MZV 48 hz.

I ran calibration with the accelerometer and get values of X - MZV 38 hz and Y - MZV 41 hz, which I have saved.

The X value specifically is quite a variance to the default value. Is this normal to see such large differences to the default position?

At this point, it would also be a good idea to post your issue on GitHub ( https://github.com/prusa3d/Prusa-Firmware-Buddy/issues). You could do so here in the forum as well, but on GitHub, Prusa can forward it as an internal ticket if your information turns out to be important.

Mods for Core One: Core One HT 450 degrees, Comfortable display , Very fast print start and Reducing noises
Mods for Prusa XL: Very fast print start

It would help if you could confirm that belts are tuned with the strobe tool, maybe also that the gantry is squared.

Also, is this a factory assembled printer or a kit? If a kit then there is no way the input shaper defaults are accurate.
