You know of course that the grid frequency is only approximately 60.00 hz. For example, it was 59.97 hz on Friday at around 5 PM. I have heard rumors that the generators spin the grid up to above 60 hz in the early morning hours to compensate for the drift, but I don't know if thats a fact. I often see the grid at 60.01 hz, in the middle of the day though.
That's true over the short term, but long term accuracy is very good.
