It is just that you may not necessarily be correct, despite the strong feelings. >If the SSDF could test all the programs against each other on the identical >computer, don't you think they would consider that a more accurate way to get >ratings than what they are doing now? They would be less accurate, and possibly useless. For instance, if I get two 1GHz CPU and put Hiarcs7.32 and Fritz 5.32 on them and let them rage against each other, believe it or not, I will have no mathematical results at all from the contest! That is because neither one of them has a measured strength. The objective of the SSDF is to provide a true ability rating that is mathematically sound. While there are always great difficulties associated with a thing like this and there are going to be problems, it is essential that the tests conducted be performed with opponents of known strength. The better and more accurately you know the strength of an opponent, the better and more accurately you will know the strength of the new configuration. The way to determine the strenght of an opponent (human or computer) is a mathematical formula that uses the strength of the opponent as one of its arguments. If this number is "iffy" (+/- one standard deviation is a large number) then the quality of the mathematical answer to that equation is also bad. Therefore, the more tests you have with a particular system and program combination, the more valuable it becomes for determining the strength of the opponents. Does it become more clear now?
