Sorry for otherresponse tomuch coffee??) To answer in a more mature tone, I do
not mind making assumptions based on data even if not true, I would make the
assumption and then I would also state I didnt feel the data was correct. I did
check with ssdf because I was wondering why Chessmaster and rebel was rated
higher on this list , then realised it was because they are using stronger
proccessors here.  For  the other list,I followed a lot of the games from before
and figure be true and since I do not have time to scour up the games and
recheck all the wins and losses of the 90 games in the message I didnt feel it
to be a bad thing at all to give an opinion based on the data above.
  Thanks ,
 Lanny
