Level 3 Point Upgrade for Champs?

I watched the Finger Lakes and WPI regionals and was surprised at the lack of 10 point hangers. Many matches there were only 1 or two robots on a side hanging. With the implied simplicity of 10 point hanging I would think every robot would be sucessful. I see an exception for great shooters, you can score more points shooting 3's than hanging for 10. Unless you can shoot 3's and hang 10 at the same time.
