Log Projection Error

References an old log projection made in October of 2014

You can see today's value for that old projection here:

wolframalpha.com/input/?i=10^(2.9065++*+ln((number+of+days+since+2009+Jan+09)/days)+-+19.493)

This script attempts to improve error based on data we've seen since the original. That ends up looking more like this:

wolframalpha.com/input/?i=10^(2.7065++*+ln((number+of+days+since+2009+Jan+09)/days)+-+18.2500)
