That was me, and they aren't that far apart. Is 41% of the area under a lot more than 32%? Not really, see this example[1] Norway here has a coefficient of 27.5 and the US was at 41.2 but the graphs are barely different except that you can see that the US has a sharp bend on the far right hand side. The gini formula is really sensitive to that in a way that doesn't tell us much.
