Matt, you're trying to argue that "direct insight" is more accurate than tournament results? Cut me a break.
Your analogy fails. Yes, Clay is obviously better than Justin. That's why tournament results are not necessary to address the question of who is better. But without tournament results, how can you address who is better between myself and Mitch? There's no reasonable way to argue in favor of one player being better than the other. On the other hand, with tournament results, you can at least point out that Mitch got 2nd at Phase 6 and that I placed higher than him at Endless Challenge, in which case you can, to some extent, assess which player is stronger.
And I never said that you can't have any rankings at all with a small sample set of tournaments. Rather, you can't go very high and remain accurate. There's no question that some players are flat out worse than others. You've already pointed out that Clay is better than Justin, and that's not open for debate really. As I've pointed out, the difference between Mitch and myself is much more subtle. It's not obvious who is better. With only two tournaments, say two tournaments where I win, it's not fair to say that I'm better than Mitch, because over ten tournaments the results may be six wins for Mitch and four for myself, in which case the result is that Mitch is better, and that result is more accurate.
Also, it's simply not fair to claim one player to be better based on insufficient tournament results, because the "worse" player isn't given a fair chance to prove that he is better. For example, claiming Spike to be better than Jamal is bull ****: if Jamal has been in several tournaments and Spike hasn't, Jamal has proven his own skill. Spike hasn't. Why should Spike be ranked higher?
Also, I can really just attack you from a semantical perspective: what do you mean by "Clay is better than Justin?" If you mean "Clay will place higher in tournaments, on average," then why aren't tournament results better suited for answering this question?
