The relationship is dependent on a smooth,level road.No curves,no wind,no rain,and a constant velocity.
It's a tough trick to pull off.The best I can do is to compare long trip data from year to year with varying mods,and document everything I safely can without crashing.
Man,that A2 Wind Tunnel is looking mighty fine!
