I couldn't think of any other good title. It's going from a heatmap to identifying individuals, who, if they didn't use an alias, are now identified. And of the 16 people faster than me on that circuit, 14 used full names.
Gave the map of the route to fake. Without that you'd need time to trace round buildings and training areas you see in satellite pics. Which is the kind of thing governments have the time to do (imagine mapmyride seeing an uptake in users in N Korea); I didn't.
