Ian, I think you missed the point. The idea is to demonstrate the most precise and perfect technique while being inovative and stimulating before a group of judges who are your seniors.
Also, by the way, to make things fun. Nothing extreme, just friendly "can you top this?" stuff. Fun. Remember when this was fun? Unless you're in the miltary or police agencies, that's why we all do this.
I remember old Baker Sensei used to say "If doing aikido makes you feel so serious, maybe you shouldn't do it...Life is joy."
