There site is no longer up so I'm not 100% on the time controls
for 95 and 96. Any participants of Aegon that remember the time controls
and mcahines used?

This would be much better, I agree. Rebel 9, I'm guessing would still TPR
out in the GM range.

 Does it make sense to use the old AEGON events, which used old

This is a kind of drawback (old machines and old software) but the
magic number of having a minumum 25 games would be difficult to obtain.

In Rebel's case it seems to have logged in a few more games against
humans at standard controls (for those who accept game 90/30 as standard).
It at least gives us a ballpark estimation of its history vs humans at
these controls. Looks impressive.
