You're being far, far too kind so I'll say it. A sample size of N=1 means absolutely nothing, it's just garbage. Unfortunately many don't know why or care why this matters - all that matters is that someone said it so it must be true. Alas . . .As far as the endurance test that Keith22 mentioned, if they are only testing 1 vehicle, I guess it's an interesting data point, but statistically is N = 1. Hardly a reliable population from which to extrapolate and predict an entire MY.
