Last year AdSense sent me an email asking if I'd be willing to have a rep look over my site and make some suggestions for better performance. I said sure, why not, and he did and sent me a JPG of how he thought the ads should be laid out. Surprisingly, he did NOT suggest I make use of all available ad blocks. I think I had to commit to trying it for 30 days. It was off season, and I did. Gathered up the data, and after 30 days, made a sort of hybrid between his ideas and my own. Having a great year. No complaints from me.
I suspect this is a wider scale of the same thing. Google has a lot of data. If all they're asking is two weeks, I would sure give it a try.
