49 Hz is impossible. It would mean that a clock using this

frequency would be slow by more than a minute per hour. 
Long-term accuracy is extremely high, precisely because clocks

depend on it. And since almost all of Europe is interconnected,

adjusting the frequency must be a _very_ slow process. So errors

of 2 percent really can't be tolerated.
