Hi Doug,

I do follow your logic, however it must then also be pointed out that in
all future editions of the Code which include this provision must be
explicitly stated the requirement for an prevailing usage assessment as at
2000 (I believe this concept is known as "grandfathering"), otherwise
exactly the type of "assessment date creep" that you outline as undesirable
will occur with successive editions...

Best regards - Tony
