Oldacura,
Remember...you are basing this discussion based on the model in your original post...which I think we agree is faulty.
So if the original model you referenced is faulty...then you cannot believe any of the results that is "spits" out.
So maybe in a perfect world, riding at 20mph with no winds...and riding at 10mph with a "perfect & steady" 10mph headwind...are actually the "similar" efforts.
I think that we also have to assume at both the 10mph & 20mph riding speeds, that we are spinning the pedals at the same rate/cadence.
Not choosing the proper gears for the situation may also modify the perception of pedaling difficulty at the different speeds.
