Multiply however many thousands of cars to our best estimate run piggy backs by however many tens of thousands of miles each one has run on its piggy back. To me, there are too many other factors involved in these far and few between cases to even have the confidence to imply (beyond a shop's diagnosis) that piggy backs directly cause or even correlate with DME failure.
