I also agree that one week is really not enough for any magician to practice stuff~
especially for teenagers~ b/c they may have problems on family issues or personal issues~
but well~ if they give 2 weeks, the audience will not feel comfortable since they dont want ot wait too long~
so it is quite a very difficult problem >"<''''''''''''
( but I also feel impress that they can create their routine in a week, amazing XDDD )
