The history of butterfly swimming

> unveiling it to the confusion of officials and competitors in a 150 yard medley race in 1933

The article doesn't say, but did the medley relay/IM become a 4 stroke event around the same time in 1952 when FINA recognized it as a new stroke? Funny to see a 150 yard event mentioned since it seems like such an odd distance nowadays.

butterfly is interesting because it's faster than breaststroke (mentioned) but slower than freestyle. it also consumes far more energy than any other stroke.

to that end, i'm not sure why it exists, except that it's truly a unique style.

* i also still hold my high school's butterfly record, 20 years on.

I never quite understood why there are Olympic medals for Butterfly swimming, but not things like "100m hop-on-one-foot sprint"

Like, why is being good at a deliberately-inefficent form of movement worth a medal in only this one case?

Butterfly is the "three point shot" of swimming. If you can do a pool length of butterfly you are a "real" swimmer, kind of like a non-prayer three point shot implies you actually played basketball.
