If you look at the error bars and the number of variables that have changed,
there is nothing stunning about it.

1.  Different hardware.
2.  Different time control.
3.  Different program versions.

In short, nothing was the same!

The SSDF tests have a small error bar, but that is for crafty of many
generations ago.

The contest in question has an error level of enormous proportions.  It takes a
huge number of games to get an accurate standing.

Also, the number of different opponents is much lower.
