In arriving at—
an average hourly rate of remuneration, or
average weekly remuneration,
under this Chapter, account shall be taken of work for a former employer within the period for which the average is to be taken if, by virtue of Chapter I of this Part, a period of employment with the former employer counts as part of the employee's continuous period of employment.
Where under this Chapter account is to be taken of remuneration or other payments for a period which does not coincide with the periods for which the remuneration or other payments are calculated, the remuneration or other payments shall be apportioned in such manner as may be just.
