I have 50.25 Hz occasionally.

Here in the USA, The GRID is maintained at 60 Hz +/- .5 Hz in Short
Term Stability... The Grid monitors, and counts each Cycle, and is
designed, to lose cycles, at Peak Loads, and make up much of those
lost cycles, during low demand, at night, with any differences made up,
on Sunday Nights, when demand is the lowest. Long Term Stability of the
US Grid is within a couple of cycles a month, and less than 10 cycles
over a Year...

I checked the National Grid (UK) site and they work to a standard of +/-
0.2Hz. They are obliged by law not to exceed +/- 0.5Hz.

You can find the exact frequency NOW here ......

49.97 Hz right now.

More info here ......

I hope that satisfies your curiosity. I happened to have a real-world
interest in finding the numbers you see.

Hey guys, there's a world out there, you need to be aware of it, or
sometimes it bites your ass.

Just remind me again, which US states have a population over 60,000,000?
