That's fine, I understand and I have read and seen those sources too, but based on my experience in working on large sites and competitive keywords, the whole caffeine update has affected the SERP and the way Google indexed pages, links so fort so on.. They probably not admitting it yet, but soon they will, the data they have collected for Google Caffeine changes have somehow reflected the SERP, I have seen it.

They have given a hint too.. "Matt says this is like changing the engine on a moving car. For now, it’s all about indexing. The suggestion is that later it could have impact on rankings."
