MAG Number above difficulty?

[Art]

Hi all, just been watching the 2012 Olympics again. Can someone please let me know what is this number they post above the difficulty?

If you look at this video, go to 3:30. you see it shows 'stop' then the number 4.31, then the difficulty of 7.00 underneath. What is that 4.31 about?

If you guys could help that'd be awesome thanks

I believe that is the vault number, telling the judges which vault they are doing. SOmeone more knowledgeable may be able to confirm or deny that

Yes that's right - it is the Vault #. 4.31 is a Kasamatsu with double twist (lopez)
