This completely ignores the fact that below a certain line, B no longer gets to participate as freely as A in the space. A gets to demonstrate higher returns as well as higher losses and still be considered a better option even though in absolute terms they have contributed greater losses than B. "Reasonable to assume, follow the trend" is just so braindead, and basically no better than flipping a coin; if you're are absent of any other evidence, then maybe you shouldn't be using that to segregate the population in to the poors and those-who-know-better.
