Why the bottom spots? Those are what will be seen just before the searcher clicks Next.
Silly as it may sound, that may in part depend on the target audience and the engine. I've seen women search as far as the 6th or 7th page at MSN for some oddball specific thing when it's something they are intent on finding and won't give up 'til they do.
Other than that, I'd agree with grandpa, though some people like #11, first result on the second page, better than the end of page 1.
