That was back in  year 2000.
Does anyone have a similar graph for year 2004-2005 to see how the predictions for the "future" (beyond 2000) actually worked out? And also is there a discoveries graph that shows how those correlate to actual productions in the UK?
Like this

As of 2004 it was down ~66% from peak. The prediction said 50% by 2005. Not bad, IMO.

Here is an overlap of a trace (red) of Mobjectivist's yellow dots (assumed to be actual production points) and the year 2000 prediction curve. Pretty close. (The yellow verticals are for aligning the year markers at 1980, 1990, 2000)
