Subject to paragraphs 5 to 7, relevant child care charges shall be calculated in accordance with the formula—
where—X is the average weekly charge paid for child care in the most recent 4 complete weeks which fall in school term-time in respect of the child or children concerned, multiplied by 39; and
Y is the average weekly charge paid for child care in the most recent 2 complete weeks which fall out of school term-time in respect of that child or those children, multiplied by 13.
