I undertand full well how an SRM measures power. But NO variation at all? No one pulls up as hard as they push down - it ain't even close. The other studies alluded to? What did they show with crank-measured power? It'd be interesting to know.
Here's the profile of the riders tested:
I'm sure your VO2Max is north of 70 ml/kg and you can maintain 350W for hours, but for most people considering a stages powermeter these riders are representative examples.
So I asked questions about the study, and you retort with
ad hominem attacks?
And what the hell is "peak power" anyway? 336W
PEAK power? That better be measured in tens of minutes....
You'd think the mere existence of a single Stages power meter were a threat to the very fabric of the universe. Or maybe the perceived valued of the sunk cost of a PowerTap....
