I am sure the ramp up is not factored into the numbers. I understand from Ace that the majority of the 2008 projects are scheduled to come on in the latter half of 2008. Production will ramp up over varying periods (months to years) for each of these projects.

As far as I know, we don't have any information about what kind of track record these estimates have for accuracy either. While these are the hoped for amounts, we don't know whether actual production will ever match the forecast amounts - or exceed them.

seems like a logistic or some kind of exp. curve would be better than a step function.
