I've never called it a lie. I think I referred to as flimsy, which it is.
I do not know why you think Exhibit 5 is "flimsy" or what you mean by that. Do you mean it does not accurately reflect Rossi's data and configuration? If that is what you mean, you are wrong. It quotes his data exactly. Rossi and Penon did not challenge the Exhibit when it was presented to them before the lawsuit. They did not answer it at all.
If you mean the technical reasons in Exhibit 5 are not valid reasons to reject Rossi's claims, then I think you do not understand what the Exhibit says, or how instruments work, or why it is a problem when you install the wrong kind of flow meter in a half-empty pipe.
If you agree with Peter Gluck that it was actually a different kind of flow meter, and the pipe was not half empty, that is tantamount to saying that Exhibit 5 is a lie. Which is where we came in.
