One sided would have been just fine. But I’ve been fighting various injuries (in both legs) and partly because of that, I recently changed my bike fit, including my cleat positions. Since then, my power balance has been a steady 53/47, always with L>R. And this is even though it’s my left leg that has the more serious injury. Not that this has a big effect on my total power, but something is going on. What is it? My current hypothesis is that my legs haven’t got used to the new cleat positions, which changed more on the right than the left (because the right knee wasn’t staying straight through its revolution). I think I’m still spinning as I did before with the left, but that the right is doing more mashing, without smooth effort through the revolution. I can work on this, but I wouldn’t have noticed it without the odd L/R readings.
