So the preview shows B&S scores as a demonstration, but at the live sighting the numbers were a bit different and not all correct so that was the real scores put on by B&S.
From this task design, the difficulty depends on whether they can solve the equation before getting all scores correct, if they need to solve the equation to realize they are wrong, it could take time to correct the mistakes (run to change scores and calculate and run to seat again). If they have a judge to tell they are correct or wrong before solving equation, that would be easier. I think production may go for the latter, but I like the no-checking arrangement more.
Was there no B&S live sighting around the stadium? It's interesting they're not spotted despite they were supposed to be leading at that point...?
