Yeah, I get that. I'm just wondering whether anyone has actually tried riding down a hill on a wide and narrow set of tyres and compared the difference. I reckon that unless you're going in a straight line on perfect tarmac, the fat tyres might have an edge.
I built a 90's mtb as a roadbike, with the same setup as my roadbike, with 44 Compass ultralight tyres. Somehow it was harder to ride in the same group as usual on audaxes and climbing felt more fatiquing. Maybe the frame is just too flexible or something. The weight was about the same.
