US GDP growth revised downwards

The previous data for GDP looked anomalous.  GDP was heading for the stratosphere, whereas almost all other indicators were slowing.  The revisions have produced a series which looks much more like things like the ISM, IP (industrial production), etc.

Here are the new data for GDP plotted against the whole economy (i.e., manufacturing plus services) ISM.  Because the ISM is a diffusion index, that is, analogous to a rate of change, it leads GDP, so I have plotted it with a 3 month lag in the chart.  The patterns for the last 10 years suggest GDP growth should slow to about 1.5%, yoy, assuming the ISM falls no further.  I think it will, though, perhaps after a mini rebound.
