Mr. Hawkins wrote that Hawk-Eye Innovations had suggested that an "uncertainty-ellipse" be shown around the path of the ball as it appears on TV, but that this has been opposed by broadcasters. I quote the relevant part of his email in full:
We have proposed on a number of occasions the idea of presenting an “uncertainty ellipse” around the ball, but all broadcasters have rejected the idea for a number of reasons:
1) Almost all commentators are ex cricketers, and generally not that scientifically bright. They would have no ability to explain what an uncertainty ellipse is
2) Broadcasters prefer a “definitive” where was the ball going – some commentators are then good at interpreting that information saying something like: “Hawk-Eye shows it just clipping leg stump, so a good decision to give the benefit to the batsman”
The ICC, in it's response through Colin Gibson is maintaining a hands off attitude to the matter, in much the same way that they seem to operate when it comes to the actual details of getting the DRS technology to work. "What is reflected by the broadcaster is provided by Hawkeye or Virtual Eye (another company some broadcasters use)". This, as Paul Hawkins' email reveals, is not strictly true.3) If the uncertainty ellipse is supposed to reflect Hawk-Eye error, then the ellipse would be so small around the ball that you would not see it around the ball
The upshot of it is, that the Decision Review System, and the use of technology to aid Umpiring decisions, is being worked out between the company or companies that make the technology, and the company the broadcasts the game. The agency that is actually supposed to run cricket is only marginally in the picture.
The point about the uncertainty ellipse is exactly as I have long suspected it to be. It has been set aside in the interests of persuasiveness, a polite word for marketability. So the way Hawkeye and all Technology works in Cricket - all judgment of what is good technology and what is bad technology, falls in the hands of the single most unaccountable, untrained group in cricket - Commentators.
Do you still believe in the wisdom of the UDRS?
