"Over-analyzing"????
Oh heck no.

Gathering data prior to a purchase to make an effective purchase is always worthwhile - unless you are Steve 0080 and buy whatever is "next" to just try it out.

The other pertinent distance I didn't see in that graphic was the horizontal distance from "nose-to-windscreen."

That's got to play into the equation somehow as well.

I'm still shopping as well......comfortably looking over the windscreen is imperative to me.

Good luck,
Steve
