Did you come up with this "rule" yourself, or get it from someone else?
A quick calculation shows that 30yrs/10mo is about 36 doublings or about
64 billion times the number in 1960.  That might work out to be reasonable,
but what are the endpoint values, so I can do a quick check?  And of course,
who is estimating these values and what is the uncertainty?
