Can it ever be truly equal? There is going to be some
overhead in having the multiple layers, so although
the sum of the rates at level N can never exceed the
rate of the parent layer at N-1, the penalties must
mean that it must be marginally less (even if this is
so marginal as to be hard to detect).
