a summersault takes more practise then a high jump. so it would take more practise to reach a high performance. the graph demonstrates a skill where little practise leads to high performance. for the same amount of practise the graph present a higher performance of a summersault then of a high jump. how can that be?and high jump takes lots of practice does it?
