Well, since we're talking about Junior, I don't really think I've seen any jumps that deserved +3. Even at Senior that's difficult to find.
But you know, I think this scoring system is really tricky... For instance, I don't think Tanos and rippons should automatically mean more GOE. To me, they're a cherry on top of the cake. They can make a jump look nicer. But the problem is that most of the time, it's the opposite. They make the air position all wonky, and when in combinations, they make them more muscled and slow(of course there are exceptions). And that's all I'm saying. Are Tanos and rippons suppose to gather more points? Yes. But only if the overall quality of the jump is not sacrificed in the process. Otherwise it will make no difference in the GOE after all.
