It's sort of confusing because all the apparatus take different times. So while they may start at the same time, vault will likely end while they're still on the third person on the floor exercise. We had a couple of favorite gymnasts or people we knew were good on a particular event and I'd be responsible for the floor exercise and call out when a favorite was starting, and my friend would watch rings and let us know when Levya would be up on that event.
The activity around the event is fun, as is seeing other gymnasts at the table and in the stand. You'll have a great time! It's also cool when they all march out at the beginning!
