Cam deviation -I am confused

[BFeller]

I am thinking about a clutch replacement. I decided to check the cam deviations. At hot idle, the values are 3 and 6. Rock steady. Run the idle up to 5000and when it drops down I see a brief hit at 7 on the side the shows a 6 at idle. Then it drops back to 6. Is the deviation that I am looking for the number at idle? The reason being is that I am considering replacing the imsb. I run a Guardian system. I have had no alerts. No debris in the filter ever or sump (when the Guardian was installed). I have a 2.5engine with a 5speed in 1998 car.

I am still reading threads to try and understand what the numbers mean.

Thanks.
