I feel fooled if it is confirmed [that Rossi and Fabiani were present at the Lugano facility the entire time, and the professors showed up intermittently] as I defended the test based on the limited presence of Rossi's team...
It have to be confirmed, because it is a huge, not only about the independence of the test, but even more on the ethic of the test team.
I also think this is an important point. The Lugano test was so interesting because it appeared to be independent, and the writeup makes it out as such, describing the minimal intervention of Rossi at the beginning and end of the test, and saying that he stepped back from it for the remainder of it. But if Rossi and Fabiani were there every day, and the professors were not, this means that once more we will have had to place trust in Rossi not to interfere. Trust that we would not have afforded him at the time the report came out. Was the Lugano test for us in the peanut gallery, and do our feelings about it matter? Presumably not. But one wonders why, at any rate, it was released to the public.
The professors were operating in the mode of researchers collaborating with other researchers on an experiment, where a great amount of trust is placed in all of the parties to be forthright. But they were dealing with a wily inventor who had up to then gone to great efforts to control the circumstances of his demos in the manner of a showman. The professors, then, if the new detail is correct, lent their name to a report that assumes the best in people, relying on the honor system when it was not warranted. That was poor judgment on their part. There were the video cameras that were running, so maybe that's something.
Speculation: we now have Levi, seeing the Lugano test and what followed it primarily through the lense of a battle between Rossi and his erstwhile funders, strongly attached to the report's conclusions and unwilling to revisit them, and reassured in their soundness by immediate colleagues; and the Swedes, on the fence about the whole thing and hoping not to become party to a lawsuit worth millions of dollars. I know the feeling of not wanting to step into a lawsuit and can sympathize with them if this is what is going on in their heads. People I know have sued or threatened to sue one another and wanted me to do something for them, and on those occasions I have very much not wanted to get involved. This could potentially explain their silence on the report as much as anything (e.g., NDAs).
