I get what you're saying and I'm not really asking you to agree with me.
And my example only took into account the surface area of one hole. Over one hole, the surface area grows so long as the conditions are met. If one hole creates more surface area, multiple holes over multiple discs, well, I figured you guys could get that one on your own
And when you think about it, you don't really require tiny holes or overly thick rotors. The radius of one cross-drilled hole is tiny anyways, the rotor needs not be very thick to meet my stated conditions.
And you can compensate for the loss in swept area by increasing the force, like many cross-drilled braking systems do (I'm thinking along the lines of the Brembo Big Red Brakes system). They just add more pistons and more braking force capability.
