(ii)the value referable to the period before the alteration or event (or the earliest of them, if more than one) shall for that purpose be deemed to have been shown in the new list, as representing the rateable value of the hereditament, as from the time when the list came into force, instead of the value actually shown in the list at that time,
but nothing in paragraph (c) or (d) of this subsection shall affect the ascertainment of totals for any year subsequent to the first year of the new list.
