I know of several people over the years who have hoped to prove Google was favoring Adwords buyers in the organic part of the SERP, but no one could do it. And they were collecting a lot of data.
I've even seen a study since Panda - and no, it didn't prove any duplicity on Google's part.
Sevral people not enough because data is in Google only. If was easy to get this data people make billions in search, not prove something. You own view but other notice huge adwords payer on top 10 always and notice that Google make much more money after Panda. All update many people vocal complaint but we see Google make more money like 30% more. For you maybe coincidence, small site disappear, advertiser site takes place and Google make much money.
