As I've mentioned in the past, this test is worthless to produce a
rating, if you want accuracy.  The "formula" was derived by letting
programs
that are on the SSDF list solve the positions, then "fitting" the
solution
times/results to make the results predict SSDF ratings.  As a result,
any
program on the SSDF will produce a result that is very close to its
current
SSDF ranking.  Any program *not* on the SSDF can/will produce somewhat
random result since it is really independent of the SSDF list.

The results are not totally worthless, but comparing a program (F5) at
2465
to a program (H6) at 2535 is way outside the confidence in the results
of
this test...

saying that the best are very close (within 100) is reasonable.  But
comparing scores is very iffy due to how the numbers are derived.  It
will
be more apparent once F5 hits the SSDF and we get real data from it...
