That's interesting .... the equations and figuring brake bias is pretty befuddling to me so I won't pretend to understand it ... but I know it can be a factor and will decrease braking performance if not considered.
One thing you didn't mention, distance from center of the hub to the caliper is a factor in stopping power. The larger diameter is not just about heat dissipation, it's also about leverage. That's also why larger diameter rotors stop better.
