I got 98% The two I cocked up I spent too long trying to align edges and geometry but actually it seems us humans do have a pretty decent hard wired equal area estimator built in. The last one - AUS/US - should be really hard but I suspect that the results are pretty good.

I'd love to see the results for this. There is almost certainly a decent paper in it.
