    It seemed like both a reasonable and easy request. The requirements were to measure the mains power grid frequency to a resolution of 0.01 Hertz, and to do it every 125 milliseconds (roughly; it could be a max of 200 milliseconds, but not much longer). Why? In this case, the chase is better than the catch.
