Certainly he was frustrated by newcomers filming 100 takes and showing just one (something I'm guilty of too!). But without being a juggler yourself it's hard to express just how much better than everyone else he really was. If being able to do a trick with N balls is unit difficulty, adding N+2 balls is a factor of 10-100 harder. Being able to perform it is another 10-100 times again.
Gatto regularly performed things the next best jugglers could barely do at all. He was the Donald Bradman of juggling, and I'm very sad we now have to say "was".
