Related aside: the genius of the Soviet school of finding athletes (emulated by others, like DPRK) is that you don't depend upon a kid trying something like Olympic weightlifting and discovering they have an aptitude for it. Instead, you screen & test the entire eligible population and focus people in the right direction early on (then keep them focused with various incentives and counter-incentives, like a nice place to live instead of a communal apartment). One might have some incredible Olympic rifle shooters or kayakers or weightlifters or what have you, but because those sports are niche in many countries those talents may never surface (so Madeleine's amazing fast-twitch weightlifting nerves/muscles are 'wasted' on volleyball instead). When you really care about medal count, all sports are important, so you want to maximize your chances of finding the right kids to put on the national squads years in the future. It's really smart, but depends upon political/economic structures thankfully not present in other locations.
