I do agree with Tissy on that. It also means some celebs have done a disproportionate amount of, say, ballroom v. latin, (offhand I think Emma for instance has done a quickstep, foxtrot and now viennese waltz, with just a jive as a latin dance). I would rather see them alternate if possible for as long as possible. It does also favour some (Peter just as an example) who do one form better than another, I believe he has done waltz, tango and now viennese waltz. You could also argue that female celebs who do more ballroom have an advantage, as it is danced in hold (can I add Jan as one who has done only one latin dance, the jive?) On the other hand, those who may possibly be better at ballroom may have done 3 latin dances. (Matt is on his third latin dance isn't he, cha cha, paso and now salsa. It does seem a bit strange really.
