The question is fairly simple. Do you want linear extrapolation? If within 1 million is good enough, then certainly linear extrapolation would suffice.
The thing about extrapolation is that it's just a linear model and you plug in parameters. And as you all know you can adjust your parameters to fit observed data. That is the criticism for nextgenwars--the numbers are "fitted".
