I would at least argue that there is method to my madness. Financial thinking as to rates of return, and comparison between returns, generally puts things on an annualized basis. I am thinking (and coding) in terms of an annualized return, and then dealing with it thusly. Domain appropriate thinking, think I. Of course lots in nature grows at compounded growth rates - it's just thought about a bit differently. And in nature as in finance limiting factors tend to intervene. Trees don't grow 4.5 billion feet high. Normally ;) Art _______________________________________________ Edu-sig mailing list [email protected] http://mail.python.org/mailman/listinfo/edu-sig
