had a gore vent fail and want to know how much water got in
Ahhh... too late. Making boards is still an awfully manual process, and there will be differences in weight in the same model.
You should weight the boards when you buy them, to have a true reference point for each board. Using the manufacturer value will always be different. ±5% is to be expected, and can be ±10% on some cheaper brands.
But of course, the factory average weight can give you a rough idea of the number of liters that came in, though :-)
PS: Also, does the weight include the pad?
