I suggested in post 87 how it could be spelled out, and the risk quantified to a degree. I haven't heard of anyone planning to include that in their rules, but I am sure GB has seen it and will consider whether it is appropriate. I didn't want to post again as this thread just goes round in circles, but if anyone picked up on the concepts of mitigating or quantifying risk, they certainly did so very quietly.
(To which is easily added a comment about kit).
