What I was trying to get at is that the difference would be a different percentage on every ride, even on the same route, unless you swerved the handlebars the same amount and degree and turned with the exact same radius and lean every time, and each rider's weight didn't fluctuate more than 1-2 lb between rides.
What am I thinking? I can put it in terms you will understand: It's like two complete strangers comparing average speeds on bike forums.
