Joe, not trying to be funny, but.
There are two occasions when you absolutely know how much is in the tanks. One of those is when they are full. If you have fuel flow and fuel used indicators I'd say you are good to go. If the 146 MEL forbids that, that's one thing. Boeing says crack on.
I bet there were some tense exchanges of words among the engineers, either before or after you went...
