If we have mistaken \(67,02\) beats to a second as \(60\) beats to a second, light speed \(c\) as measured would have gone further by a factor of \(\cfrac{67.02}{60}\) so
\(280.735414*\cfrac{67.02}{60}=313.581457438\)
because we have a longer second (\(\cfrac{1}{60}\) as oppose to \(\cfrac{1}{67.02}\)).
What happens at or about \(67.02\,Hz\)? The length of a second is in doubt.
