Yes, although I'm not sure of the exact percentage. I think they discussed it in one of the API threads, try searching around.
A lot of people have tried that approach... and it's worked for them. You may want to consider breaking from the pack... Attempt to suck. You never know it could work.
Great info...as always informative AND interesting to see what you will get in response. Ill pass it on...suck = bad Thanks Gents
The fact it is included and 6% of the score were the answers I was looking for. Just a little joke thrown in there.
