Here is the data plot for hacked rice cooker using rice that had been soaked overnight:
It was my assumption that soaking the rice overnight would greatly reduce cooking time. As can be seen from the graphs, the cooking time is reduced, but not greatly. I'm measuring cooking time by the time the power is on. But even with the power cut, the rice will continue to cook for a long time, since it is insulated. Note the long temperature decline curve.
