And what good does knowing this do? I'm serious. I mean if you have
fun keeping track of this that's fine with me. But what nutritional
value does it add? Will you eat more to make up a "deficit" or eat
less because you in "surplus"?

Yes. If I burn more calories than usual on a given day, I'll eat
more that evening. If it was a particularly long day (5000+ kcal),
I'll even eat two dinners. I'll still eat the same amount during a
ride, just to keep from bonking. I can't afford to lose any weight,
so the calorie monitor keeps me from doing that.
