That is great, now he only got the purpose wrong.

Below is repeating what I already said:

OP's purpose was to disprove "that the 5Dc would outresolve the 60D at some point" - to prove that hypothesis can never happen. To prove what that, he needed to shoot a flat surface with a imperfect lens. for example 50 F1.8 at F1.8.

Well, all lenses except the 300/2.8L II sems to be "imperfect". The 24-70/2.8L II scores 11 P-MPix on 7D (60D isn't available) and 12 P-MPix on 5D.

I think these numbers come from lens's best FL at best aperture. not the worst case scenario, which is what OP really need to show to prove his point that "that the 5Dc would never outresolve the 60D at any point"
