Read the blue box that goes along with R06 .... It basically boils down what people like me (Humble Inspectors) think about your application of the thin edge. We may or may not think it's a hazard to the playing field and/or people in and around the field. You also may get a different interpretation of it's safety at each event you attend. It's best to not push the boundary of the rule too close in this case.
