close enough, thanks. This indicates at least that we're not talking about two
completely reactions but rather preferences. fwiw, at the -0.8 setting with
current master, 1cm on the touchpad maps to ~1cm on the screen and the screen
cursor feels like it's just a tad slower than the finger, a movement not
triggering any acceleration eventually has the finger overtake the cursor.
While that's acceptable for something that close to the lower range limit of
-1, it would be way too slow for anything above.
At a speed setting of 0.9 the cursor is effectively uncontrollable. Any faster
movement hits the edge, a fast ~2cm movement crosses the whole screen. Again,
for 0.9 that's acceptable because it's the upper range. But I'm really curious
that you want such a slow default speed and such a fast acceleration. I tried
your curve and the pointer is almost uncontrollable for me. When acceleration
kicks in it shoots to an edge way too quickly, I end up overshooting by 5-10cm
on anything but fast movements. So what's going on here?</pre>
