I don't think it's a put on in any way. They are flying at 10/10 ths, I don't see any stage management from the pilots.
As for some of us getting and doing as well as them.... I've done a fair bit of aeros and have been flying for a while, but there is no way I could just jump into something like an edge and do what they do. Very few people could.
I'd love to get good enough to though! Practise, practise, practise.
