I looked at the video and couldn't say with any certainty where the ball finished.
I thought players announced their ball and marking on the 1st tee? If so, wouldn't other players be able to at least repeat the make, number and marking...assuming one could see that far up the tree? If not, players should be more aware of each other's ball so they can at least offer an opinion for identification. Pro players are so detached from each other that its hard to believe they can really attest cards with much level confidence.
