Well, I would have thought that once a temperature sensor reads 100 deg Celsius the clock would start. I'm sure there are good reasons why this wouldn't work well or is overly complex, but I would expect the article to discuss them.
From the article:
> Fumiko found that heating the water and rice to a boil and then cooking for exactly 20 minutes produced consistently good results.
That knowledge about the ideal timespan of 20 min seems to be completely irrelevant to the implemented solution.

Partially. They also mentioned that it was generally believed that you needed to vary the temperature during cooking to get fluffy rice. Fumiko's discovery is just as much about the fact that you can use a straight boil the whole time as it is about the duration.
