I'm a little stuck... Click here to teach me more about this clue!

'this amount' is the definition.
(par is a kind of amount)

I cannot understand how the remainder of the clue works.

(Other definitions for par that I've seen before include "Rating of strokes required for hole (golf)" , "Rap for being average" , "Normal level or standard" , "Average score for round of golf" , "Usual or expected level" .)

I've seen this clue in The Globe and Mail.
