Um this logic is faulty. I certain hope Google doesn't rate that way.
Person visits site page 1, spends a minute on it.
Person selects page 2. Realizes its not what they want after another minute.
Hits back button to go to page 1.
After a second on page 1, because they have already seen it,
they notice an adsense ad that is something they want to know more.
So they click after a second or two of page load time.
I am sure that happens every minute of everyday somewhere.
I also really doubt that google filters smart pricing that tightly, it's too subjective.
It is probably more related to page rank and internal/external backlinks, etc.
Considering there was a Google deepbot crawl at the start of this month,
it is easy to believe the value (not to mention traffic) of clicks has changed on a wide variety of sites.
