Balance plates. Who's right, Who's wrong

hopefully that makes sense.
I knew someone would try this angle, but NO it is not "flipped" it is rotated 180*, other than the off-set bolt holes it IS still 180* rotated. If this still confuses you, disregard the direct comparison and focus on the fact that each plate was mounted on the crank individually and produced 2 different balance results, the objective is both should have produced identical results, to the tune of 19.79 in.-oz. factory spec, so once again, which one is more accurate to oem spec.
and the cumulative difference is 20g?
Good word choice, maybe both are not right.
