I seriously doubt that.. the practical application of developing the skill sets needed for dancing at the higher levels, is not acquired by simply performing in a concentrated time period of ANY measured length.. they are nigh impossible to measure . I was considered a quick "study " in my childhood, and I danced several days( nites ) a week, yr in and yr out..and in my teaching career, i,ve been fortunate to have some very gifted (?) students, Pro. and Amat. and the progression rate even when accelarated , would not have achieved a standard, that would be comparable to the scenario that was given .
The amount of material to be mastered at those levels over 4 / 5 dances. from scratch, is monumental.
I will give you this for an e.g... when I arrived in the States, I decided to work for A/M and they ran an 8 week course covering 8 of the social bronze level dances ( 10 variations in each ).. I was at that time a prof. with a members degree. I STILL found it demanding to accommodate all the nuances of a new standard... so, is it poss ? maybe, but I,m not convinced..
