8.—(1) After calculating the amount payable to each claimant as provided by regulation 7, the Minister may, if he thinks fit, increase that amount by a fixed percentage provided that—
(a)such increase does not exceed 20% of that amount; and
(b)the percentage increase is the same for each claimant.
(2) If the amount payable to a claimant by virtue of regulation 7 and paragraph (1) is less than 90% of the compensatory allowance paid to that claimant in respect of the year 2000, he shall be paid, in addition to that sum, such further sum as is necessary to increase the total hill farm allowance payable to him to 90% of the compensatory allowance paid to him in respect of that year, or, if less, such proportion of that further sum as relates to the claimed forage area which was entered in his area aid application for that year and which lies within a less favoured area.
