--- Comment #7 from Brett Kerwin <brett.kerwin at mamber.net> ---
Running the finger around the touchpad until the figures don't change any more
does not provide the same values consistently.

The maximum/minimum values that I am typically able to obtain after trying
really really hard are "x [79..1841], y [140..1325]".

Once, I was able to get "x [0..1825], y [102..1320]" but I am completely unable
to reproduce this.  More generally, to get any value below 80 for the x
coordinate, I have to center the finger off the touchpad, so that only the side
of the finger brushes the touchpad.

Typical values that I get by keeping the finger on the touchpad and going as
far as I can (trying hard) in every direction are "x [87..1928], y [166..1316]"
or "x [87..1832], y [170..1311]".  I've just done this twice and the figures
come out different, after stabilizing; that's how it is.
