Yes kind of .. this is an physical inaccuracy that leaks into the software from the domain model. Naming it acceleration would be incorrect to. Since the cursor speed is actually a scaling of the acceleration curve - which is a curve providing the actual speed scale based on the amount of recent movement. Where recent movement is the relative steps we were able to observe from the device.
I could offer a similar confusing comment to clarify things.

Oh I didn’t realize.. Soon this is one of the values that is planed to be configurable by the initial pocket desktop ui.
