Just a random thought. I have a friend who is a Pro of Psy. He speaks of "game theory". I was in the Air Force in the mid seventies. We had a pool table there and I had never seen such strict rules. I have thought about it ever since and I think it was an "evolution'' of game theory that took place. It may be that someone says "you're cheating" and a new rule is made.....and year after year rules built up with no way of stopping it. I have seen this recently and again, new rules were made up that might not have been necessary.
Or to exclude competitors. I saw this racing in NHRA and it was based on eliminating competitors.
