(1) So soon as may be after the occurrence of any windstorm in respect of which the Authority receives any return under section 8 or considers that it is likely to receive any such return, the Authority shall for the purpose of complying with section 10 cause an inspection to be made of the affected holding in respect of which any such return has been made or of any holdings in the region or locality within which they consider any affected holdings are likely to be comprised.
(2) So soon as may be after the completion of any inspection under subsection (1) every inspector shall, subject to the directions of the Authority, make a report to the Authority either—
(a) estimating the percentage of loss of ratoon mats suffered by any affected holding in respect of which a return under section 8 has been received by the Authority; or
(b)
(i) containing a fair estimate of the incidence of loss of ratoon mats in the region or locality to which the report relates,
(ii) specifying the various areas within such region or locality which in the opinion of the inspector have suffered an approximately similar percentage of loss of ratoon mats and the boundaries of such areas,
(iii) estimating the approximate average percentage of loss of ratoon mats suffered by holdings situate in such area.
(3) In making the estimate referred to in subsection (2)(a) or 2(b)(iii), regard shall be had only to the number of ratoon mats which, immediately before the windstorm in respect of which the inspection is made, were growing upon an affected holding which is inspected and have suffered loss by reason of that windstorm.
