HI Jeremy,

0 100 250 300 299 300 250 100 0
actually registers as 2 fingers.
This patch updates the logic to ignore small dips in pressure that
are
less
than the threshold.
Does it still detect 2 fingers as 2 fingers when they are held
together?
I just wanted to follow up on this patch[1], since I haven't seen any
movement. It's fairly trivial and I've been using it for the past
month with great success (yes, it still detects 2 fingers properly).
Is there hope that this change can get merged soon?
Thanks,
Jeremy
