Scottyboysdoll, I think it would depend on the syllabus/dance. Compare, for example, American Foxtrot and International Foxtrot. In the former, the Bronze and Silver (and Gold) levels differ significantly--they are like two different dances. In the latter, one doesn't "move out" of Bronze level.
Sadly, many dancers who dance silver American smooth often "forget" how to dance the bronze figures.
In the Waltz, too, the International syllabus preserves the basic character of the dance at all levels. Whereas, the American silver syllabus incorporates passing of the feet in many of the figures. This, in my mind, often renders the dance little different from the Foxtrot, save for the timing.
Perhaps you're referring to rhythm/Latin, which is a whole new kettle of fish.
