The point is that even with this relatively crude evaluation, you are attempting to draw conclusions about the relative performance of cars but you have no idea which ones are more affected by the inaccuracies of the fixed-floor tunnel. By your logic above, it seems to me that the cara with larger wheels are suffering a larger penalty from this tunnel because of their larger wheels.I understand the expense and challenges of a rolling road tunnel. There are few in the world that will accommodate a full size car. But that's no reason to assume that a fixed-floor tunnel gives accurate, or even meaningful results. Have you ever compared results between two tunnels? I know someone I can ask about that.
