The bottom line is that Westexas uses the term "accelerating decline" to describe quantities which decline by a constant, unchanging amount year after year.

No, he did not say that at all. He said:

our expectation is for a long term accelerating rate of decline in worldwide net oil exports,...

He said absolutely nothing about a constant, unchanging amount year after year. An accelerating rate means an accelerating percentage of decline each year.

Whenever the words rate of decline or increase are used, then percentage is automatically assumed, not actual numbers.

It looks as if John Denver stumbled and fumbled over some fairly relatively innocuous math.

I wonder once he understands the mistake he made that he might change his outlook toward a more pessimistic outlook? .... I kind of doubt it, he has made up his mind.

Yes, and whether it's accelerating or not, peak economy still means we have trillions of dollars of debt to "unwind." Or, said another way, the bankruptcies and other debt defaults are just in their early days.

Collapse has begun.

What I find particularly silly about JD's misunderstanding is that in some cases ELM does predict accelerating export decline in absolute terms, for periods of time, and not just acceleration in year to year percentage decline. So he's accusing westexas of using exaggerated language when in fact westexas may be understating the direness of ELM predictions.
