I suspect that it's more mistakenly generalized than erroneous - at least there are indications that they are the result of a (somewhat) scientific study. Which is why I asked for the source - perhaps there are details available. The skinsuit was very specific, but one wonders what the "regular" jersey was. Also, what kind of shoes benefit from shoe covers, and what is a "tuned" tuck, etc.
