GoFWR you may have known about hole 81 but I certinly did not nor expected it. It was a total surprise. It was so to many others and that is why the spike in sp occured and not due to some testing as you imply.

If anyone wanted to test sellers than there were better times before the news and since.

Most spikes occur faster than declines afterwards - that has been my observation.
I disagree with everything you posted in the two posts.
