The ELO Range averages change everyday, it goes up and down. playing 5000 games yourself isn't going to change anything. If there was a flaw it would have shown up by now, approaching 3 million games. It would take a lot more then one person to make a ELO RANGE Average go down. The other (example) 500 users of The King 3.33 would have to stop playing all together. On the other hand, if he renamed his engine to The King 3.33_200mhz, His rating would appear on the list after 5000 games. This is shown in the ELO RANGE. The King 3.33 2513-2543 ELO RANGE Average of 2528 +/- 15. >However you may get slightly more meaningful statistics by introducing a lower >limit of number of users for each engine: e.g. only allow it into the charts if >at least 40 different people have each played more than 50 games with it. That >would tend to average out the hardware strength a bit better. 2000 games is shown at the playchess.com link above. However, it doesn't give you a range until 5000 games. It's not as accurate at 2k games either. >I don't know >whether you can do that with the raw data available. No I cannot do what with the data. Joshua Haglund toneewa@yahoo.com
