If not specifics, has anyone ever come up with a "Rule of 72" style rule of thumb approximation?
In general, on a flat, energy is required to overcome air resistance, and a little rolling resistance. On a climb, energy is required to move weight against gravity. There is no standard work equivalence factor.
