While amusing, I'd like to point out that the accuracy stated for this law doesn't meet the precision that the parent poster stated (0.1°C).
Supposedly accurate to within a degree Fahrenheit (which I think is .6 to .7 Celsius). With the more reliable snowy tree crickets, it might just approach .1 Celsius accuracy. It could be interesting to read more about this, but there doesn't seem to be a plethora of scientific research that I can find easily.
