Spike, I think your golf analogy mis-represents the actual situation. Let me apply the EMH to golf and maybe you will understand.
The Pro golfers are the ones who win the big money. Most of them have been playing since they were like 1 -3 years old. This means that, if you or I would suddenly aspire to be a pro golfer using *publically available techniques*, we could work very hard all day for 10 years, and we would only be as good as the Pro-golfer was when he was 11-14 years old. So the Pros would always beat us in the tournaments. However, if we developed a new technique to play golf, then we could surely win some of the lesser tournaments. I'm sure if someone had the interest they could become an expert at projectile motion and perhaps even apply general relativistic corrections in order to take non-standard routes from the tee to the hole. (For example, anyone who has been playing golf for some time knows that a golf ball bounces WAY farther off a cart path or a tree than the fairway.) With high processing speeds available in pocket computers/Palm computers these days (not to mention what might be available several years down the road), one could do the neccesary calculations in the short amount of time required. I hope this analogy helps.
