It's not speculation. Are you asking for more of a deeper explanation of how the internal API works, or do you want to see published papers/links about it? Google doesn't publicly document the "Google Analytics Internal API".

Please provide some evidence of this claim as it relates to this extension:

> when your data is collected "Google" gets it, processes it and then pushes the refined data to "Google Analytics".

You are asking for a publicly available document showing the architecture of Google + Analytics + Doubleclick + Adwords... I can't get that, but other than doing experiments; you could do what I did when I first found out which is go ask someone who works on the internal API. (That's what I did)
