Trust is good, control is better!
I have already been measured three times with the motorcycle and then I always had to turn up to half the rev counter and then measurements were taken. So at 14k rpm was measured at 7k rpm. I have no idea whether they have to, can or whatever, but these are my experiences.
Homer: "Children, there are three ways to do something: the right way, the wrong way, and the max-power kind."
Bart: "Isn't that the wrong way?"
Homer: "Yeah, but it's faster!"
