7. If, after the application of section 6, the number of sales entered on the basic list is lower than the number of sales to be entered on that list, as many sales as necessary to make up the difference shall be added to the list from among the sales concluded before the second fiscal period preceding the fiscal period for which the median proportion is being determined.
The sales entered on the basic list in accordance with the first paragraph shall be determined based on the reserve chronological order according to the date on which they were concluded and, in the case of sales concluded on the same date, based on the descending order of registration numbers.
Notwithstanding the foregoing, no sale concluded before the fourth fiscal period preceding the fiscal period for which the median proportion is being determined may be on the basic list.
