grinding, as there is nothing available to quantify the finished cam to. This is a real problem for the grinder when checking the Jerk or 3rd derivative of the production cam, as Jerk can get very large in all the wrong places during grinding without the original data to compare. Jerk is basically the rate of change of the rate
