Thanks for a good, helpful post.

Tony's calibration page is at http://home.interact.se/~w100107/level.htm

I welsome the SSDF's openness in publishing this data. Unfortunately, I don't
think that it provides strong enough evidence for the year 2000. The following
claims can reasonably be made:

* Humans have improved against computers in the last 10 years

* Even allowing for the above, it is possible that computer "rating inflation"
has occured since 1990, in which case the current SSDF ratings could possibly be
too high now

This is why we need to look at the evidence of the Israeli league.

However, thanks again to Chris and Tony for being open with the "older"
evidence.
