I don't know the answer to your question, I've never paid enough attention to the graphs. I would like to point out though that our own graph is lower than it should be for the last turns due to building research, which at least in the demographics screen numbers add those hammers to the GNP instead of the MFG. I suppose that's the spike in our GNP graph, I'm surprised not to see a similar dip in the MFG graph.
