Al, once again you are spot on. I think that the reason the OR is included is that few people will make the observation that you just made. It takes an UNDERSTANDING of these principles to get what you see. Unfortunately, many won't put in the long yards to get that intimate knowledge of the game. I don't blame people who want a quick fix, on the contrary. But, I do think that a deeper understanding of the game creates a more well rounded player, IMHO.
