Yes those are the correct stats. You also have to take into consideration that version 15.0 has played 426 more games vs tougher opposition (19 elo.. not much I know) Make 14.0 vs 15.0 and I _guarantee_ that 15.0 comes out on top. It is the stronger of the two versions, although the SSDF list doesn't state so. For CT 15.0 to have the same rating as 14.0 after almost twice the number of games clearly states that 15.0 is stronger. Allow 14.0 to make up the 426 games, and I will bet my left leg on it that it will not maintain the same rating. If you take Fritz for an example many still believe version 7 IS stronger than version 8, even though the list reflects an 8 point margin in favor of version 8. Peter
