@markr,
True enough, Markr, about the Games being so short that sub-games are not needed.
But, even though you or I may not do too well in the 1-29 game, we may do okay in our little league, perhaps even contributing to our league winning over another league. As a game huckster, that is important.
Which leads to the observation that the Games may have begun as contests to determine who was the fastest runner or whatever only to devolve into beach volleyball and which country brings home the most medals.
(in the 2nd grade, by the way, I was singled out by the nuns as "the best blackboard cleaner in the entire school." It was a proud moment for me.)
