Mr. Raby shot down this idea at the time......my memory fails me at to why

Take a ride in your car once fully warmed up with the Durametric system monitoring cam deviation values any you will have the answer to your question. With the valve timing system active, the deviation values jump all over the place, depending upon what the car is doing at the time; so a system that alarms when a certain deviation value is hit would be doing one of two things: Alarming every 15 seconds if it is set too low, never going off if it is set too high. It would also be comparatively expensive, as it would require something with computational capabilities to even work.
