I have been checking the SSDF list as others have by running are own tests and I
have found the SSDF list to have a high degree of correlation with my own test
results. Can anyone show were the SSDF list has been grossly wrong in it
rankings of computer programs? I can not think of one that has stood the test of
time. I remember some programmers claiming their programs were the best but SSDF
tested poorly and with slow machines. I know some of you know what programs I'm
referring too, but these claims have been proven false.
