Statement-A:
""Look at this: say these three top acts are incredibly stronger in chess
strength than all th other 500 (which is apparently NOT the case in CEGT!) then
what you are testing in such little 20 or so games matches? Are you really
testing chess strength? I dont think so.""


First: You said that yourself: "which is apparently NOT the case in CEGT!"
So the testing is logical to be done this way......

Second: Since all top engines play again each other and also against other
weaker(we care only for the first in this case), the engine's strength testing
is correct and we have not a situation described in your statement-A.

Third: Since all non-top(weaker) engines play again each other and also against
the top (we care only for the first in this case), the engine's strength testing
is correct and we have not a situation described in your statement-A.
