(b) (i) The highest final average remuneration to which the participant would have been entitled in accordance with article 1(h) if he or she had separated from service on 31 December 1984 or on any later date preceding the actual date of separation shall be applied to the participant’s contributory service up to and including the date on which that final average remuneration was first attained;
