Great information.
I was curious and managed to locate a little detail on the fuzz and other arguments.
You can find that
fuzz: specifies fuzz value that is used to filter noise from the event stream.
Which means that the input system in linux will drop events generated by the device driver if the difference from the last value is lower than the fuzz. This is done in the input layer.
Another user posted:
So it would seem that any changes less than fuzz are should be filtered out / ignored.

The Device section talks about the fuzz argument.
