I’m not much into dyno numbers.

I agree with most of what you're saying.
I can't speak for all dynos but in my case hardly anyone comes for a bragging rights dyno sheet. Around here people are pretty tight lipped about their motor program.
I'm curious, how do you view a chassis dyno?
I think a chassis dyno is a good tool too......probably better since it includes the whole car. Even still, all you have in the end is information........which is good, but time slips are better. lol
