Dear JAG members,
We received Helge's latest projection just yesterday, and I was away
yesterday; so I just got to look at it today. Therefore, I was only
able to do a very cursory analysis. Still, this is enough to show that
his projections continue to penalize JAG harvests unrelated to JAG
recommendations.
In the latest projection, he modified his January 15, 2011 projection
(MF-IV) by modelling 1/2 of the Matrix using JAG prescriptions and 1/2
using the 2008 MP prescriptions. He found some increase in projected
harvest rates in the first five decades, but harvest rates are still
significantly below the Option A projection.
The attached chart shows why Helge's modeling assumptions lead to such
low harvest rates for the JAG recommendations. Basically, Helge assumes
that JAG recommendation cause harvest rates as a percentage of growth
and inventory to be far below those projection under Option A. The JAG
did not recommend such low harvest rates; thus Helge's latest
projections have no more relevance to understanding the JAG
recommendation than his earlier ones.
Perhaps Russ can make copies of the chart for our meeting tomorrow.
