Reply #11: It is preliminary data that suggests the immediate need for more study.

The pre/post fukushima data set makes sense on its face. Since its a bit odd, the truncated period before Fukushima should be explained, but off the top of my I can think of a couple of possible and valid reasons that might have made limiting the data set to 4 weeks the right thing to do.

I'd like a more complete discussion of the reasoning but I'd not dismiss the evidence offered based on what I've seen so far.
