Sgt_Kickaxe, I think the concept of automating your site based on GA stats is an awesome idea as a means to protect it from Panda (and, I believe, as a means of maximising rankings for your most important pages).
It's just a matter of getting the right process for assessing what is bad content and then dealing with it in the right way. I'm not sure that a page is bad just because it didn't get search engine traffic within a couple of weeks. I'd base the judgement more on whether the new page was popular with people already on your site (did it get lots of internal visits, did they spend much time on the page, did they stay on your site....assuming it's a page that you wouldn't want people leaving from). I'm not sure two weeks is enough time either, although it may depend on your volumes of pageviews.
Personally, I don't believe noindexing is a way to protect your site from a bad page. I think you either need to remove it, or noindex it and move it somewhere where people can't easily find it while you improve it (but Google can so you it knows you've de-indexed it). I think if people can find a bad page, bad user stats are being produced which can harm your site.
The problem with automating it completely is every page is different and, because we don't have access to the stats of our competitor's sites, we don't know where the line is (in terms of stats) between a good page and a bad one for a particular topic/keyword/whatever.
I'm working on a similar idea but it's more of a flagging system. I have some basic parameters that, for my site, hint at a bad page and it makes me aware of pages slipping towards the bad end of the scale so we can look at what's causing it and decide what to do. However, the we are finding that it's still very complex - pages that were great last month (according to our stats) can suddenly become bad pages and the cause can be anything from competitors undercutting us on that product to a drop in interest due to seasonality, bad weather or world events.
What to do in this situation is proving to be a challenge, but we do see that our rankings can be negatively affected with a couple of weeks if we hang on to pages flagged by the system as having shifted into the low quality camp, ignoring what the possible consequences might be at the next Panda refresh.
We're introducing new pages very slowly now, giving them lots of internal promotion as well to push lots of traffic in so we can make a quicker assessment and decide whether to keep them or drop them. We've only been doing this for a few weeks and although we've not seen any improvement from the last Panda refresh, we are seeing the rankings of some of our category pages improve as a result of this overall approach, which I'm hoping is a sign we're moving in the right direction.
