Comment(by manuq):

 I don't see intolerable jitter in os15, XO-1.75.  But still feels too
 fast.  I can reach the edge of the screen moving the finger a bit more
 than half of the pad, at some speed.  If I lower the velocity, works
 better.  So I think it can benefit if we lower the acceleration level.

 I like ELAN, it draws better curves than AVC, which tends to square them,
 makes more angular curves.  Sample pics trying to draw clouds with each of
 them:
