Someone remarked that the accuracy of 60 hz is good, and that over-frequencies would cancel under-frequencies. I would really doubt that they could do that to any great degree of accuracy. The grid is the largest machine on Earth, and there is more than just a single generator.
You may have heard of the power grid. With the grid, many generators, in many locations are synchronized with each other. You can be certain this also involves holding the long term frequency stability to 60 Hz.
