We also hope our filters end up in mainline and it's nice to hear you
are using them.

How many filters are you using?

I will update the "group" filter and it should be better than the one
we have now (requiring less points when there is no much noise
present). It should help you discard your noise and it might allow you
to use the median filter with less points.

8 samples sound like it is not enough but then we would have to see
actual samples.

Could you send a few samples? Let's say, make a number of clicks and
send them so that we can check how your data looks like. It would be
nice to know how it is for other hardware.

Something like:

x0 y0
x1 y1
x(n-1) y(n-1)

for a number of points would help.

What we've noticed now is that fast (light) taps can usually have a
lot of noise so ignoring them is not a bad thing. It would be nice to
see if we can indeed do better.
