It just occurred to me that if everyone has the exact same routine, it must not change much. You could be doing the same, rote routine for months if not years. That is 75 -90 seconds of steps linked exactly the same way all the time. The prep for the beginning of pattern B, is always the finish of pattern A, and so on. Apart from the boredom and lack of artistic expression, that strikes me as poor pedagogical technique for preparing a student for the next level. Silver to Gold would be bad enough but the jump to Open would be vast. Variety and novelty is necessary for physical and mental growth. Otherwise the brain gets stagnant and the body habituates to the challenge.. No kid ever became an enthusiastic and competent reader by reading and re-reading the same book for months.When a pro has multiple competition students, having everyone dance the same routine at the same level is a necessity. One possibility is a pro can to start the routine at a different place, a couple of measures in or something like that, if that's feasible. Of course, that is predicated on the student actually knowing their part in the routine and feeling comfortable dancing what might end up being a last minute change.
