Bad habits established in mainstream just get worse by the time many dancers get to challenge.
Short-cutting do sa dos, promenades, left allemandesm etc. happen all the time a challenge, but why I don't know. It's actually easier to do them right and feels better. The reasons are mostly for conservation of energy and to have fun. I like changing a do si do to a swing or something else because I find that call awkward in its original definition and not pretty in its execution. I enjoy doing it.
