Yes:

Regression
Analysis
R =	1.00    Correlation Coef.
SEM =	18.1    Error of measure (2 SEM = 95% confidence)
Slope =	231.4   (number of SSDF points per 6x speedup, or per ply)
                (this means 77 points for 2x speed increase)
                (this would be for both hw and programming improvements)
Y intercept =	272.8

Note: The regression analysis changes slightly as the SSDF continues
testing (new lists), but not a whole lot (maybe 10% over time).

Best Regards,
