AB, that's my point. What could be the nature of any other relevant information? Suppose that on his trial run he could have dinged at his previous rate. One has to assume that wgt would then have reinstated him and said, "Well done, you've passed the test."
It would appear they can't detect an auto-dinger nor a packet editor present on any particular computer. Remember, they said, "Tell us what auto-ding program you're using so we can learn more about it." Of course he couldn't because he wasn't using one.
He was the innocent victim of a flawed security sweep that was compounded by a faulty assumption on wgt's part.
That's where the speculation that there must be something more to it falls apart. What more could there be, unless they paid someone in Indiana to look through his window while he was playing?
