Yeah the behaviour runs around a bit, but my results seem to be pretty consistent. I just tried moving my pointer around each of my screens without mode-switching, and got the following results: Just the internal: Average for abs deltas: x: 22 y: 14 Median for abs deltas: x: 18 y: 12 95% percentile for abs deltas: x: 62 y: 39 Just the external: Average for abs deltas: x: 32 y: 19 Median for abs deltas: x: 30 y: 17 95% percentile for abs deltas: x: 80 y: 50 > You also said above: > > A slow pointer makes me press harder. > > Please make sure you're not affected by the speed of the pointer motion on > the screen.

I think that this is exactly what's happening, but it's also possible the the firmware is sending larger inputs in response to longer straight movements. > The instructions to hit the screen edges are just so users know what to > roughly do, the tool isn't affected by the visible pointer movement at all - > the trackpoint will keep sending events even when the pointer is at the > screen edge.
