--- Comment #2 from Nate Graham <pointedstick at zoho.com> ---
Gladly! One thing that I notice from the recordings is that I get pressure
values that are around 40-60 when the thumb is resting on the bottom edge, but
80-110 when the thumb is resting somewhere away from an edge. Fingers, by
contrast, register as 40-60 when away from an edge. That might be a good way to
detect a resting thumb.

The recordings I'm about to attach show the problem: with the thumb resting on
the bottom of the pad, pointing occasionally triggers two-finger scroll
behavior, and two-finger sctolling almost always does nothing (perhaps it's
interpreting it as some kind of three-finger gesture?)
