Being asked "where did you get that from?" I have to shrug my shoulders frequently. Leg or step projection is an well-stablished and a well-known leading concept. But actually who invented that thingy? I´ve learned from stage and nuevo dancers. Neither of them followed this concept. The first got something like "sink or swim", the latter got the concept of "active following" instead. Also most ballroom-ies I´ve asked never have heard of this concept, too. So finally I suspect Susana Miller. Can you help me? Do you know quotable sources or at least an author´s name?
