Quote: I don't know when you determine a kid has "peaked out"?
I know a kid can reach a level when they hit a ceiling, but I would consider that temporary. I wouldn't consider it "The Peter Principle".
I would move the player a level down, into a situation (hopefully still competitive) where they could succeed and still enjoy playing the game.
Re-read my post, because that was my point. When its not fun anymore...slide down a level and start having fun again.
You don't like Peter Principle then how about Survival of the Fittest? The higher you go..the rarer the air. All these kids are athletic, focused, hard working. If a gap develops between your kid and the rest of the elite pack, can he/she catch back up? Of course....but doing so means you child must improve at a faster rate than those in front of them. Not an easy thing to do....considering again that the kids are athletic, focused, etc.
Trends can be reversed but the likelihood of doing so is limited.
