It can be done very easily - but for sure they are not doing it now "realtime" to change the serps. If they collect this kind of information (and i would) they have done it earlier to collect a LOT of user selections which they add as a factor to rate a certain page.
One should also not forget the Google Toolbar ... this little baby delivers nearly everything you need regarding user behaviour / selections combined with querys..

Thought I'd mention it just in case nobody else had. Do not trust these results!

2 things to consider though:
1) Sometimes you can refresh a query on certain datacenters and you will get dramatically different results with each refresh.
2) I believe the results at mcdar are based on a query that shows 100 results per page, which will sometimes result in slightly inflated numbers.

There's nothing even remotely blackhat about my site. It's static HTML with no frills - no Javascript, not even any images - except for AdSense. It has huge numbers of (almost entirely unsolicited) incoming links, from all over the place, and almost no SEO has been done on it (page titles are derived from book titles).
The only thing I can think of is that my AdSense alternate ads are causing a problem. For a while I had myself convinced that was the explanation, but the more I think about it the more implausible that seems.
