Of course. But we've also tested road equipment on the velodrome, and those measurements are consistent with road equipment in the wind tunnel and in field tests on real road surfaces. And when we've tested road tires and tubes on smooth rollers, we get the same results as when we test road tires and tubes on the velodrome or on real road surfaces. So wind tunnels, velodromes, smooth rollers, and field tests produce consistent results when the same equipment is used. And when we tested groups of riders on the velodrome or in team TTs on real roads in real wind conditions, we get consistent results.
The big picture is that thus far we haven't seen a situation where the ordering of drag (inertial, rolling, or aero) is different in these different situations. The absolute measurements, of course, differ but not their ordering.
