The 80 points was, at least in the past, a generally accepted number for doubling the processor speed (has this changed, or am I wrong). As for my ply numbers, I freely confess I just pulled them out of the air. If my guess was too high, then I would pick 10ply and 9ply. But the underlying argument that going from 5 to 6 is greater than 9 to 10 is what I am supporting. Another response to this post suggests this "80 points" number may apply only to computer-computer matches. Which makes sense, since it's been a long time since SSDF has been touch by human ratings.
