The SSDF should NOT try to select a number one UNLESS they have played enough games to be sure they have the right program selected, taking into account the margin of error. I'm sure this is a nod in the direction of marketing hype, but for commercial chess programs, the marketing force HAS to be very strong, otherwise the program probably would not exist for long. You have a point Rolf, but it will be buried by market hype, and that's life. The whole SSDF rating work perhaps can best be thought of as a longer tournament - ie., the strongest program may not win the top spot (because enough games are not played to differentiate all the programs), but that's tournament life. Welcome to SSDF life. All in all, you have to really appreciate their work, if not every little aspect of how they present their findings. Dave
