Even Christophe explained that to you. even christophe is mistaken too. ok - i do explain it to you. you can stretch a feather, and it will react dynamically. but than, suddenly, you come to a point of no return. and than the feather breakes and the reaction is massive. or: you can drive on a motorway to the left, to the right, to the left, from one side to another. now speed up. it will still work, but be more difficult. suddenly, you come to the point of no return, and the car drives out of the path, the dynamically movement stops and develops into a chaotic movement. you get a car crash. now take 2 chessplayers. they are arround 50 elo different. the machines are similar. you get reasonable results. like the car driving left and right. or the feather. now take 2 chessprograms. they are arround 100 elo different. lets call them junior-shredder2. they are running both on 450 mhz. junior kills shredder. but the car is still on track. it will not crash. its within the range that produce sensible data. now take shredder2 from the 450 mhz and put it on the 200 mhz. now junior6 450Mhz fights vs. shredder2 200 Mhz. and suddenly. you come to a point where your results do not anymore only show effects of the programs, as the car crash is not only a reason of the car, or the feather, but of the overstressed material breaking. suddenly the results become worthless. like letting kasparov playing a 1500 ELO guy. of course the 20 games match between kasparov produces measurable data, as much as the car-crash produces measurable data. but what both things connects is: 2800 ELO vs. 1500 ELO produces not very sensible data. the data you get crashing on the motorway does not tell us much how good the car drives. it only shows that you overstressed the physics involved. junio6 - shredder 2 is withtin the sensible range. if both run on 450 Mhz or on 200 mhz. but junior6 on 450 vs. shredder2 on 200 produces results, no doubt about you get data, but the data is as senseless as the data the broken feather produces, or your car, when it crashes. or when kasparov plays you. you get elo-points. but they do not really be relevant. >Are you allowed to criticize the SSDF methods of testing? of course i am !
