Its not over my head. I think that fact is going over yours. Not sure why you insist that i don't understand how percentages work.
Using % for ingredients is not a common practice for US produced foods, regardless of the legality. By listing like ingredients individually one really doesn't have a gauge as to what to expect.
Will this have the first few ingredients as the predominant flavor or the combined lesser ingredients be more of the forefront?
Plus, you even pointed out, its a marketing thing. Marketing is not about furthering consumer literacy, and i find so much of it to be less than sincere.
How many restaurants have truly have a world famous endless wing bowl?
Then again, how many places have endless wing bowls? Seriously on that one. There is one place that i know of, but its like $18 and they buy their sauces from Sysco.
