What you are trying to do is magnificent.
Let me reiterate that you have a very low bar to "magnificent." me356 dragged a group of people halfway around the world on false pretenses. He reneged on his agreement at the last minute. He let them do four days of hard work testing a machine that does not work, while -- he claims -- there is another machine in the next room that does work. It would take a half hour to hide the guts of the other machine to do a black box test.
If this is "magnificent," I would hate to see behavior you call rude, pointless, or reprehensible.
This field suffers from lax standards. In any other scientific or engineering discipline, me356 would be shut out until he does a proper test with the equipment now on loan to him.
