I can't remember if it was Cat or Cummins that did a test on this very thing.
It was Cat. During every warrenty repair done on all late model, computer controlled engines a print out of certain running parameters must be printed and submitted w/ the claim. If it is a fuel consumption, noise, or oil consumption complaint the first thing they want to know before you ever get started is Idle time and percentage. They will deny a claim in a second if idle time is to high, though I can't remember what those magic numbers are.
