Review comment:
This does not seem to be required, as total is a calculated value.

Review comment:
Adding a fake state only for testing metrics collection does not seem
right to me.

Review comment:
Nit: Can this be converted to a loop over all states summing individual
values? That way if a new state is introduced, no further change in counting
totals will be required.
