Strictly Come Arithmetic

While watching Strictly Come Dancing (yes TV to the rescue again), I noticed a contestant was given a 7 by each of the judges. My brain immediately set to work and inside my head, I muttered to myself, "Oh, 28". Genius, I know. So, Strictly Come Dancing can be used for some four times table work. Maybe screenshot the scores, maybe make your own, maybe watch a dance that's given four of the same score (to engage the class) and ask the class to quickly work out the total. Of course, we can not do any of those here due to copyright (Have emailed the BBC to ask for permission though - they always say no though).
There's more here than just the four times table of course, it's mental addition. Score of 6, 6, 7, 6 is 3 X 6 + 7. So now all scores given are useful. Again, take screenshots, make your own, watch it back in iPlayer. I like the idea of seeing part of the dance for a bit of context. How quickly, and most importantly what methods are used, to get the total score given?
