Sorry Mr. Kamisato, but as detalled and rigorous as the study you cited may sound, I suspect what I think are its artificially precise projections are simply straight-line extrapolations of past and present data into the future.  Perhaps this report include a range of low, medium, and high versions of projected "continued growth" based on "business as usual" assumptions.  

But if it did not consider possible discontinuities and  alternative scenarios other than mildly different versions of continued growth, then I think the utility of this study as a valid planning document is limited if it does not include a wider range of current, emerging, and possible future threats and opportunities--which I think are usually missing from conventional thinking and planning efforts.  

For a few examples of what I am referring to, please see my other comments in this thread.  But if you disagree, please feel free to enlighten me.  Aloha:)
