the 1992 Order shall apply as if, in Article 3, references to the calculation day were references to the day immediately following the relevant decision day and accordingly, subject to sub-paragraph (b), interest shall accrue under that Order from that day onwards (including that day); but

notwithstanding sub-paragraph (a), interest shall not be payable by virtue of the 1992 Order if payment of the full amount of the award (including interest thereon) is made within 14 days after the relevant decision day.
