I will just do it now in a friendly way. Regardless of the advice you get from Mr Nesbit the COA will blow you off on any stewards decision if all you do is second guess them. You have to provide NEW EVIDENCE if you expect them to overturn any decision. The steward has the option to use their judgement as far as on track incidents and the COA will not touch that unless they were negligent. They will look at video or witness statements not available to the first court. Cheap learning experience for you and all reading.
