It's just nice to have a gone though motor. Where you know all three sensors are half way straight.
I won't say dyno numbers are meaningless totally. I use mine to dial in a motors timing, find out when it needs a new rotor or to compare motors of like type. Also valuable to get starting rollout numbers for oval racing. But I am a experienced racer and a experienced dyno user.
