"You also need to consider that when Google finds new content and deems it news worthy that it will rank it higher for a week or so and then you will start to see it slide."
That's only for QDF keywords. Some keywords are newsworthy, some are not (http://www.youtube.com/watch?v=o4hH4ZQ_19k). I don't think this particular keyword would be considered a QDF.
"When the site/domain name linked is not in a proportional relative to the number of links and varied anchor text expected out of the whole of links to a site in the same niche it could easily be considered unnatural in my opinion.
In other words, if you have 95% of inbound links with the site/domain name as the anchor and most in your niche have 58.3% with 41.7% being varied, yours could be unnatural (not like the others)."
I don't think most websites in any niche have any common or similar anchor text variation. Anchor text variation differs from site by site, not niche by niche, IMHO.
The site that ranks #1 for the keyword is an exact match domain that has about 90% of inbound links with the site/domain name/keyword as the anchor (according to ahrefs), which is much more than mine, which has about 75% of inbound links with the site/domain name as the anchor text, and mine isn't an exact match domain.
"which would I think include an expected rate of "new link finding" relative to number of pages spidered over time, etc. but maybe I'm missing something?"
I don't think it's logical to say that there is a correlation between the number of pages spidered over time and the number of links found. I could find lots of counterexamples to this.
"How about click-through from the results or click-through, click back (or search again), click on another result, meaning the search did not end on your site/page (iow your site was not the right answer)?"
Since my site is new and hasn't gotten any traffic from Google yet (it was ranked on page 6 before, which nobody goes to), this data wouldn't be available yet for my site yet, or any other new sites.
"I'm curious how they would not use click-through, click back (or search again), click on a different result as a factor to indicate whether your site/page was "the right answer" to a query or not."
There could be lots of reasons why people click back, search again, or click on another result. Many queries don't have just one simple answer that users are looking for. What if you're searching for reviews or opinions about something? You would probably click on multiple search results to get as many opinions as possible. And that wouldn't mean that those sites you click back on are low quality.
