Fair enough, but those are professional riders, I actually think the gap of improvement with us may be higher than a second, because most of us aren’t pushing these bikes to their limits. If more of the bike’s speed is accessible to us then our margin of gain in real life is improved.
If the old bike was at a 10 and the new bike is at a 10.5, pecco improves by 0.5
But me and you are only riding these bike at 6 out of 10…if we move to a bike that lets us ride at 8 out of 10.5 then me and you got ALOT faster.
Accessible speed is more important than top possible speed for guys like me and you.
