For this to be true, it would have to be a measure of strength equivalent to playing games, IMO (at least ignoring books, time management and stuff). Imagine if everyone starts developing for years only to score high on that suite. Do you think the one scoring the highest (assuming they don't all get 100%) will also be the strongest? It's quite obvious it's not that simple in general, just compare speeds of CM and Fritz in finding mates and see how that relates to their chess strength. To make a balanced suite where these two engines end up close to each other you'd have to find a whole different set of positions where Fritz scores better. Now you take a third engine, say Junior, which scores badly on the Fritz suite and the CM suite because it has its own set of strong and weak points. So you have to add a new suite for Junior. Etc. for a fourth engine.... This kind of reverse engineer patching of a testsuite will by definition produce the right strength relations, but still it does not indicate strength. -S.
