What metric would you propose?
It is physics based. Think of the equations of motion, particularly going uphill and then descending. There's your answer. Since the bikes are physically captured inside of trainers, the handling and technical differences between riders are negated. This is power/weight is all that remains, beside the psychological elements of tactics and pain threshold.

I think that you answered your own question right there...
