Who said that and based on what data?
Don't have those details in my head and too tired to dig them up. Might, MIGHT be able to find the thread quickly. I'll try.
I think this is the thread:

Warning--the naysayers trashed the thread up one side and down the other.
I didn't examine the predictions that closely but trust some of the people putting stock in them.
I don't know if what you are looking for is there in that level of detail or not. But that's the best I can offer you tonight.
I need to get to bed sooner than later.
