I'm with you Jaykay, I believe monitoring the cam deviation in concert with a chip detector is the way to go. Alarm at 5 degrees?, I'd go with .5 degrees. Any fluctuating deviation is not a good thing, slop is slop.
It can't be hard to monitor those two values and then trigger some sort indicator. This can't be that tough to figure out and then we can all sleep a little better at night. I'll get right on it.
