How accurate do you think it is???
edit to add: FOR THOSE WHO THINK THIS CHART IS INACCURATE CAN YOU PLEASE SUGGEST A BETTER RESOURCE ?
ALSO, can you be specific? For instance, "no its not accurate" is not helpful. Instead, perhaps "My experience coaching 200 skaters suggests that the average total hours to master the double axel is closer to 3000 not 2500" or "This chart looks fairly accurate but only for elite skaters."
Sorry to be so snarky but I'm not sure why you posted these questions. Several posters (including me) were kind enough to explain why they disagreed with the chart but you seemed to discount their comments.
Then why ask? I'm seriously confused by what you want here. You asked for our opinions and expertise. I (we) gave it to you and still you want to follow your chart that is not accurate.
My sentiments exactly!
