I think I should email them and get an "offical" answer.

Nutrician facts are only required to be within ~25% of the real value for a typically prepared item. And that is before rounding. For example, an item with 0.6 g of fat on average can be reported as 0.45 g of fat (25% less). Then they can round. Clearly, you would want to round 0.45 g down to 0. So any item with 0.6 g of fat can be legally reported as 0 g of fat. Lovely little loopholes the goverment allows. They call it an allowance for "product variations".

Of course vitamin and fiber content is usually fudged up by 25% and then rounded up.

The net effect is that you can't just compare two products and assume the fine details have anything to do with each other. Even if they are similar products from the same company.

The two patties should be approximately double the values of one patty. But don't ever expect the numbers to be exactly equal.

Awesome. So those nutrition values are really nutrition estimates +marketing.

Can't trust any source of information anymore.
