Props to Diesel Dave for exemplary performance.

Much of it is due to his recognition of the importance of road speed in the road load equation.

Aero drag HP goes up with the cube of road speed.
Everything else is proportional to road speed.

Few people (me included) can keep their speed down like DD.
