4.B.9.—(1) Calculation method A is the aggregate of—
(a)the amount that would be payable under Part 3 if—
(i)the member’s discrete period of pensionable service as an officer were treated as pensionable service as a practitioner; and
(ii)the amount of pensionable pay received in respect of that officer service were treated as pensionable earnings as a practitioner for the respective period;
(b)the amount payable under Part 2 (if any) if the member’s pensionable service as an officer were reduced by the discrete period of pensionable service as an officer in sub-paragraph (a); and
(c)the amount payable under Part 3 but for the operation of this Part.
(2) Where paragraph (1) applies—
(a)the member is entitled to count part of the period of officer service referred to in that paragraph as a result of a transfer-in under regulation 3.F.10 (acceptance of transfer value payments); and
(b)the transfer-in is other than a transfer-in referred to in regulation 3.F.11(6) (calculation of increase to pensionable earnings as a result of a transfer-in),
for the purposes of any calculation under regulation 4.B.2(1)(a) or 4.B.3(a), the amount of the pensionable pay deemed to be received in respect of that part period of officer service must be calculated in accordance with regulation 3.F.11(2).
