<pre>in touchpad_accel_profile_linear the value of
const double threshold = accel_filter->threshold
is crucial.
For me, it is defaulting to 254
This speed is hardly reached; it represents very rapid motion on the P50.
the threshold code is basically not of any practical use because the condition
if (speed_in < threshold) {
factor = 1;
rarely happens.
I've attached an experimental idea which is working quite well on my P50.
the threshold now depends on filter->speed_adjustment
and the accel function is simplified</pre>
