Right, there is no clear cut defintion ortimeline.

To me, expirience/knowledge is related to the amount of effort put towards making good desicions when the moment of truth arrives. It's two part; not just spending time practicing, but having a few notches on the belt as well. It's easy to say what you would or should do when on the internet, but all that talk drifts in the wind when a big buck offers a debatable shot. How you perform in the clutch.

Knowing you can make the shot and actually doing it are not the same.
