Missed focus is not an exclusive feature of mirrorless or DSLRs - all systems can fail under certain circumstances. The idea of a confused PD AF module because it is sensitive to a bigger spectrum of wavelength is something new to me, but makes sense.
"How does that compute?" good question, but in reality I see differences between all kinds of lenses on a certain DSLR, be it genuine or third party ones. I also see differences depending on distances between camera and subject. If lenses just work fine, they might be slow ones or always used at f/8 at infinity. In my experience it's a win in the lotto if one lens needs no AFMA.
