The fact you were wearing a half-unzipped windbreaker one day and a skinsuit the next, or that you forgot to top up your tires with CO2 one day on your road bike, is not included.
Right, I'm kinda cheap and do not have any power sensors.
That's why averages over a number of rides and looking at top 80% and 20% - it helps eliminate the day I was riding into a head wind or it was pouring rain or I was just tired and dragging a$$. Same rider, same course allows for a good amount of leveling (no skin suit in my closet). And power is the final word, so without power, I feel I've done a good analysis.
