Yep, understood. And I understand it matters for racing, or the rare long distance/fondo type people.

I'm just not sure how much of this applies to the majority of recreational riders. Most of us ride to time limitations - so going slightly longer distances doesn't change anything. Even if we do "train" a bit. X amount of time at X amount of watts is what really matters. Speed actually means nothing in this sense, and an extra 1/4 mph really means nothing - comfort is actually king. Comfort can help keep the average Joe on his bike longer.

Don't get me wrong - I like riding fast. Well, fast in relation to my abilities. I do enjoy the speed. But 22mph vs 22.5? I can't tell the difference. My computer can, but I can't.

Most of us, well actually just about all of us - are slow in relation to the real fast guys. Many are really slow - but, you will see B-C group pacelines with a bunch of duffers riding aero bikes that don't fit well, and as mentioned above - they can't get into the aero position anyhow - and may be in a worse position aero wise than if they had a bike better suited for them.
