However, if your ergo samples at 100Hz, or 500Hz, then you're very likely to put up much higher numbers.
I didn't know that about not needing to be accurate at all power ranges to claim a certain accuracy. Interesting.
I did know that about that about Garmin headunits only being able to sample at 1 a second. I'm writing my dissertation on power meters and have had to take this into consideration. Either way it'll be interesting to see what they come back with.
