Why don't we forget about absolute ratings and make them program-relative
instead? The SSDF list would look like this:

T12         0
F532      -25
N732      -33
N99       -52
H732      -60
J5        -77

It has the advantage of being equally informative about the relative strength of
programs, without giving a FIDE-like rating that is anybody's guess and way too
inflated anyway. Does it make sense to believe that Tiger (2696) is as strong as
Karpov (2705) and Kasparov (2715) during the 1984 World championship match?
