That doesn't make sense to me, but it may well be for some people; I don't know. Maybe you've got a scatterpoint and a linear regression on it.

I was just saying that in my experience, I didn't see any significant difference at any point between my left and right pedal strokes, and am happy with a Stages. It always connects. The battery lasts a long time, they're pretty cheap, etc.

In your chart above, some of the Stages plot points are more accurate than some of the SRM plot points, and SRM is always held up as the gold standard. So, I think it's a decent argument to say that a single-sided power meter, whether it's a pedal or crankarm, can work just fine -- especially for someone like the person who started this thread.
