Is it? :) This may have been already answered by the SSDF. Programs running on a P90 are on average 78 points weaker than the same programs on a P200MMX, which is roughly three times faster. This amounts to some 50 points increase when doubling the speed. The SSDF list might be more accurate than the NPS matches because of the many more games played and because programs running at 10x won't have enough RAM for hashtables to compare reliably the impact of increased time (speed). In early 80's doubling the speed was supposed to increase strength by 100 points. About 10 years later, Larry Kaufman said it would be 70 points, and now in the SSDF list is 50. If it is true that the doubling in speed is having less and less impact in strength over the years, this might be interpreted as a confirmation of the law of diminishing returns.
