 The spatial derivatives $\partial_i$ are evaluated by comparing
 neighboring grid points, corresponding to a second-order stencil
 evaluated in the middle between the two neighboring grid points. 
-Second-order decay is assumed, hence $p=2$.
+Although strictly speaking different variables or even different
+components of tensors can fall off differently, we find that
+using $p=2$ works well in practice.
 
 As with the initial conditions above, this boundary condition is
 evaluated on several layers of grid points, starting from the
