As for dissipation through the wires, my numbers are based on published data from the manufacturer. I expect that it is safe to assume that the manufacturer's test rig included appropriate-gauge wires, and therefore that their data therefore includes heat dissipation through said wires, but it would indeed be preferable to know more about how they gathered that data.

The ideal thing would be to gather some data firsthand using a test rig that is specifically designed to replicate the conditions found on an FRC robot (match the wire gauge, crimp and terminal styles, wire length, and air circulation)... For now, however, I'm content in the knowledge that my current level of precision is good enough to get a working idea of what's actually going on inside the breaker.
