Google certainly must have study results on common user behavior. Anything that appears excessive and repetitive is easy to spot.
3 clicks is neither repetitive nor excessive.
It could also be that if someone has a pop-up blocker installed it takes them a few clicks before they remember to hold down the control key (or whatever override their software uses).
All regular publisher's AdSense opens AdSense ads in the SAME window, it doesn't launch a new one, so this won't be a problem. Only a few premium publishers are opening AdSense in a new window.
My webserver log however shows that 46 visits which came with the ad referrer (and - yes - I'm ONLY counting the retrieval of the HTML document and not the images).
I agree that multiple-clicking from the same user to the same ad is not uncommon behaviour. And my logs seem to support this.
