. In that case, surely the pro partner's choreography skills make a huge difference to the outcome? Some of them seem to be really good at showing their celeb partners off to their best advantage (although, admittedly, it's hard to compare since the celebs all have different aptitudes).
It also explains why some of the pros have looked... less than comfortable... doing the Charleston! 
I'm a Strictly newbie, and had no idea that the jive was a standard dance - it looks so different from the others! It must be very difficult to get right - the only one I've enjoyed so far is Ashley's.
