My point is that to the untrained eye, a kick about on pontcanna fields will look the same as the world cup final. When it comes to skateboarding you have an untrained eye (as do I- that's not a criticism). There is a reason the kids at your skate park are not competing in the Olympics. Yes they are scored for style and that will be the difference. Some will be very good at it and go to the Olympics; others will not be and won't.
