We built a somewhat better thermodynamic model into the Pantelligent iOS and Android apps -- i.e. user would select 1" thick steak, medium, and then we'd use the real temperature signal to adjust the cooking time. The key fact this simulation is missing is that the outermost layer of the food quickly becomes dehydrated, at which point its thermal conductivity drops dramatically. This is good! It allows for much more uniform internal temperatures. Edit: we did a lot of thermal simulation using my CircuitLab simulation engine (https://www.circuitlab.com/ https://www.circuitlab.com/) -- circuit models for thermal simulation are common, where voltage represents temperature, and current represents heat flow. The simulation engine allows for arbitrary behavioral elements like algebraically-defined resistors, which lets you model this "outer layer dries out" behavior quickly.
