Are these time controls for past AEGON's correct?

400(W-L)/N, and the performance rating in general, is not very good in extreme
cases (short events, extreme ratings).  Otherwise I play a match vs. Kasparov,
lose all games and get a 2400+ performance.  If I can get the full crosstable
for the Dominican Republic event, I can do the regular round robin rating
calculations on it, which involve all participants, even those without FIDE
ratings.  Does it make sense to use the old AEGON events, which used old
versions of Rebel with slow machines?  This is a problem when trying to rate
computers - they are moving targets.  Humans can learn (kind of like a software
upgrade), but they can't upgrade their hardware (yet).  I guess we can use them,
and say that Rebel's rating lags behind its true strength like a rapidly
improving human's would.
