It's likely you are, if your points are failing with a peak built up on
one contact and a pit on the other. Maybe it is possible to tell by which
point has the peak whether the capacitance is too high or too low, but I
don't know which way it goes. Trial and error is your best bet; up the
capacitance a bit, and if it gets worse, back it off.
