what part of that did you not read/understand?
has nothing to do with conversion ratios from day to day, and i'm sorry a 500 MILLION year swing is quite a fucking leap no matter how you look at it, far too much of a swing to be considered a "close enough" or "just a little off"
That'd be like oracle saying he makes sales daily when in fact it's once every quarter of a million years.
500 million years  slight miscalculation eh?

Well, I guess it would be a wast of time to discuss with you about the nature of statistics.
For the others:
Anyway, the magnetic field has changed often in the past and it will continue to change it's polarisation, these changes happen on average every 250 million years and it takes a loooong time compared to human lifespan to complete such a change, so chances are good that your compass shows you the right direction tomorrow too.
BTW: The magnetic pole is about 2000km away from the geographic pole and keeps drifting away a few kilometers each year.
