Subject: Inflationary Effects?

Go up one level in this thread



The main message is that SHREDDER 7.04 dominates the field by some 40 points,
approximately the same as Kasparov leads the FIDE ELO list.

The 2800+ figure is not meaningful, as stated elsewhere here.

I heard once that there was an inflationary effect built (incidentally rather
than deliberately) into the ELO system.  I don't know if this is true, or if so,
why it is true.

But if so, I would expect the SSDF rating list to 'inflate' faster than FIDE's
as the same number of games happens in a shorter time.  I don't know if ELO
ratings can be pegged back on a fairly frequent basis to counteract this.

One could compare the top-figure trend in SSDF v that in FIDE.  Did not SSDF peg
back all its ELO ratings by some number like a 100 some time ago?

Certainly, some mechanism to correlate the two ELO lists would be welcome.  This
has to involve computer-human play.

To encourage the human side, the computers should not play on the latest N-wide
rack-mounted-PCs server but on the sort of kit that SSDF are using.
