This is in clear violation of the J1321 protocol.
If you use the proper calculation, the fuel saving is in the 2% range, as expected.
How can you argue when the facts are obvious?
Wait, you said the Amsoil test vehicle got worse MPG. Now you are changing your tune?
You can choose the readings from the test to get the numbers you do and Amsoil chooses the most consistent under 2% numbers. I don't think that's cheating or a violation of protocol.
