Tried those two too. After reading what they do I hoped that it may help, but
no. The result is not really what I look for. IIRC, changing these values did
not helped in fixing the jumps and made the cursor move not in a smooth way. 

I mean something like, at touch, start counting some finger motion, once a
predefined motion is achieved, stop counting and then start moving the cursor
normally.
