I'd agree with it for the most part, though it really should be a bit higher for the maggie death stroke. Also, it's odd they didn't include good old freestyle. Butterfly is underrepresented, but I expect this because it's the hardest to learn and to do well and it's not as energy-efficient as the others. But when you do learn it and get in the groove of that motion, it is by far the best feeling of all the strokes.
