Naum 4.2 - FRC Ratings List updated

[Ray]

Naum 4.2 64-bit has been added to the ratings list. The pure list is the one I prefer:

It is showing as approx +44 ELO stronger than Naum 4, so the author's estimate of +50 ELO is sound. The statistical error margins with just 700 games here are still quite big.

I am running matches against some more non-pure list opponents, to get the game count over 1,000. The error bars will be a little less, plus we'll see if the rating moves.

200 more games added to the ratings list. They have lifted the rating slightly, so now Naum 4.2 shows a +48 ELO improvement

A further 200 games have been added for Naum 4.2. It's rating has improved again, and is now +51 ELO after 1,100 games. Alex would no doubt be pleased
