I think the final thing that needs to be clarified to distinguish between Evan's interpretation and the interpretation adopted by Travis and I is what it means to be inside a feature.

I don't think that a ball can be inside a ramp. As a contrast I believe that a ball can be inside a playground slide shaped funneling feature. In my opinion such a feature complies with the rules if it is 3" deep or less.
