Does Practice Make Perfect?

Does Practice Make Perfect? I just heard a swim coach working with a masters club. She said practice makes perfect. What she was teaching should never be taught. I don't think practice makes perfect, do you? Not if one is "perfecting" defects............. However what the coach was practicing should be taught in all con-artist schools. I have seen, personal coaches, sitting (probably counting the un-earned money in their heads) while their student (singular) was churning up and down the pool, creating huge whirlpools and whirlwinds and barely advancing. I wish I had a camera (and that Ottawa public pools allowed filing or even photography. My films of some of these swimmers would have made the finals of "America's Funniest Videos" because even non-swimmers would LTAO (replace the T with an M and you'll know what I meant).
