The thing that gets me is they have to know it’ll need to be reproduced under some kind of controlled condition eventually. Unless they were planning on a Theranos style fake it until you make it strategy, I have to wonder if they aren’t sincere.
That’s not to say I think they’ve necessarily achieved their claim. If their procedure is as incredibly fiddly and measurements as subtle as I infer from the stuff I’ve read, that’s a lot of chances for mistakes and noise.
