I'd debate accuracy. Accurate enough depending on what you want to use it for... Data logging fine, aero testing not!
My biggest concern with one leg PM's is just doubling left leg power. Due to pedalling asymmetry and how it varies depending on the level of effort with individuals, if the imbalance ends up being greater at harder efforts, then the degree of variance from actual power will be greater. Now if pedaling asymmetry was consistent for a given level of effort, then you could suggest it is repeatable. Unfortunately this isn't the case as pedaling asymmetry at a certain effort can vary depending on fatigue and other factors.
