"Personally, I would be most worried about asking questions then arguing with every single answer given, especially with the number of years experience those you're arguing with have, even more so when those years of experience are combined."
I just think that one can never be too sure about Google's ranking factors just because they might have seen correlation in their data. After all, correlation is not causation - this is especially true in SEO and unfortunately, it's something that most SEOs often forget.
"So you would click through, click back (or research), click again at a similar rate across a number of sites, which would mean there's not a distinct variance between the rate of one from the other, correct?"
Not necessarily. What if some pages have more/longer content than others? It would take a longer time to read them but that wouldn't necessarily indicate higher quality. I just don't think one can extract conclusive data about the quality of a website(s) from SERP click data.
