Much like the field events, it's the fastest at those defined strokes.
Otherwise why do we need to know who is best at throwing a flat round weight, a ball, a ball on a bit of chain and a long stick. Just make it a beanbag and be done with it.
Also you can blame an Australian for butterfly stroke (trying to swim breaststroke faster by lessening drag), and Melbourne was first time it was in Olympics apparently.
