Er,  is this Chris? :)

It's a dilemma. The SSDF would give better estimates, but only for older
versions with different books. WMCCC gives unreliable estimates of the
relative strengths but for recent versions. In fact the only thing
important is that the relative strengths are distributed like in an
average tournament. Given the programs at the latest tournament, an SSDF
based estimation would be most reliable, I believe. It doesn't all have
to be very exact of course, just realistic.

What would you guess are the chances that Hiarcs would end in the top 3?
Personally I wouldn't be suprised if it only happened 50% of the time.
