| From: Michael Galea via talk <talk@gtalug.org> | When I say 60.XX, its me thats truncating | the digits (not the SEL).. | From: Lennart Sorensen via talk <talk@gtalug.org> | So an average of 59.991435 for that sampling period. Remember, he truncated the values (grep does not round). My best guess: the average of the readings would be from a distribution centred on 59.996435 (0.005 larger than Lennart calculated). It could be as low as 59.991435 or as high as 60.991434, assuming six digits of precision in the fraction. I know nothing about accuracy of the device. Summary: the 60Hz hypothesis is not excluded by the evidence. Far from it. P.S. "grep -c" eliminates the need for "wc -l".
