Technically this is a Kihon (a strike, where as a Kata is a series of movements) - but since Codewars ranks each Kata with a Kyu level and 8 Kyu is for beginners, it just uses Kata and not the term Kihon. To your point, at some point in the future it might be nice to separate the challenges out into the 2 distinct concepts, but for now there is no issue here with simplicity.

Yeah, but that's not really an issue, though.
