I don't think Kara was robbed because she didn't get 40. The dance was beautiful, no doubt about it, but having watched it back a 2nd time some of her footwork was really bad. Len commented on the heel leads that had become far too exaggerated (or whatever word he used), but even worse - for me - was when in promenade position, instead of dragging her left foot towards her right foot, she picked it up and stamped it into position. Maybe she was thinking tango was like paso, where lifting the foot is acceptable, but for a tango it was completely wrong.
