Perhaps then you could just summarize how you concluded that .07% precision was achieved.
By looking at the graph in Miley's slide presentation in which he is making measurements in the single-digit MILLIWATT range and observing the S/N ratio in that data.
I look at dozens of technical stories over the course of a week. Maintaining a set of links "for argumentations sake" is simply impossible, and quite often when I "do" make the effort for someone, I can't find the exact same "stuff" a second time.
But in this case, I was lucky. Unfortunately, I'm a work now, and the link is on my machine at home. When I get back to that machine, I'll post the link.
