Craig, if you go to the same rolling road, you have exactly the right idea about how RR's can be of benefit.
Going to different rolling roads and expecting a meaningful result each time is foolish IMO. But, if you use the same rolling road each time (which is likely to have the same operator each time) you can at least have a meaningful idea of the changes to the power and torque that your mods have made.
