Has RY DQd himself with the evidence in front of us and we didn't spot it?
He needs independent verification that he has run what he is claiming. This can be from the RV driver. He has shown us the log where someone physically signs their name next to his mileage.
In the desert according to his blog, he went off by himself. Who signed the log? If it was a crew member then they have already said that they weren't with him, so they lied. Surely if he had had company (another runner) it would have been mentioned in the blog. If no one signed this, then it wasn't independently verified?
