IE so far, I have not seen _any_ evidence that says 2x faster today doesn't help as much as 2x faster a year ago. Many "feel" that there must be some sort of asymptotic behavior but so far there is no proof. In fact, there is ample evidence that for the next few doublings, we will continue to get just as much improvement as we did in the past. Newborn wrote a paper discussing this. Heinz followed up with a verification experiment. Both show that deeper searches will _continue_ to improve playing skill for a good while yet. yes, it is very probable that 20 years ago a doubling would be worth more than 70 points. But it seems to have stabilized to around 70 for a long while now. And no, I am _not_ talking about each doubling walking the computers up the FIDE rating list by 70 points. I doubt doubling is worth much at all when playing humans in the top 30 or so. But in pure comp vs comp games, give me that factor of 2x every time. It will swing the balance in my favor for a long long time I think.
