it’s more of a ball park range.
They are actually very accurate. About 93-97% acurate usually.
The only thing accurate is how long you’ve been slaving away in your sweat…
Its pretty straightforward to measure the amount of power you put into the machine. The innaccuracy would enter in estimating the efficiency with which the individual user’s physiology converts food energy to mechanical energy. Stride efficiency, etc. I’d be surprised if it was any better than +/- 10%.
