How many trees is a rookie?

Hey all, Im new to the boards so please be gentle on me. I started out rec climbing. Then progressed to trimming with a hand saw. Since then I have removed about 20 trees. I have been to a few seminars and 1 climbing compitition. I have quite a bit of gear and have been rigging down the removals. Saftey is always my first concern. I am also insured. Now, knowing from experiance(in life) that you are never really done learning, I was wondering what this board feels is a graduation from rookie arborist. Thanks for your input.
