OP calculates the Eigen Grandito, which is named after the Onion article, "Taco Bell's Five Ingredients Combined In Totally New Way", which, in more mathematical terms, asserts that Taco Bell's dishes are all linear combinations of the same ingredients.
I was just explaining to my wife that I thinking of cooking as a vast recipe space which includes all possible recipes and the ones that have been published are point-sampled linear combinations/orders of basis ingredients or dishes. But I figured it was pretty obvious that TB is simply weighted combinations of basis tortillas.
