A perfect A/F ratio means everything is dialed in and unless you may a weird change it should stay that way or relatively close for a long time.

I hear you bro but I must once again vehemently (big word alert) disagree, you see a modern day vehicle with Throttle Body ie fuel injection makes thousandths of calculations and adjustments a second in order to have / maintain that "perfect" air fuel ratio
our carburated trucks don't have no computer so they don't adjust much as we drive them, they don't know weather its 50° F when we start them to drive to work or a 105° F they don't know if we is towin' or haulin or are alone in the truck or with 2 of our fat buddies
so our trucks do need constant adjustments, I think you are focusing on the Idle circuit too much, I am thinking of the entire big picture, WOT - Wide Open Throttle, Part Throttle, cruising, but we'll get to all that, stay [ahem] tuned
and I have started a separate thread for all this to get even more geekier with it for those of you who want to follow along
