--- Comment #11 from Peter Hutterer <peter.hutterer at who-t.net> ---
grab this branch here:
https://github.com/whot/libinput/tree/wip/touchpad-accel-debug-output

build it:
https://wayland.freedesktop.org/libinput/doc/latest/building_libinput.html

then run sudo ./tools/event-debug --verbose

Move your finger on the touchpad and look at the "touch movement" message
whenever you lift a finger. What acceleration factor do you usually get?
Note that this sums up the deltas, so stick to straight lines to make it
mentally easier to map to the distance traveled.

Also make sure that the mm distance is correct, just in case.
