par for the course

Originally a phrase used in golf. Ironically, completing a golf course in par (or even net par) is actually unusually good for most golfers and is not a typical result.

• "It took a long time to finish, but that's par for the course on a project like this."
• "[…] Nigella Lawson and Ralph Fiennes, we were told, might pop by later. The Gopniks smiled calmly: this was all par for the course for them."
• "The extra scrutiny was a sign of the times, but having never IPO-ed a company before, most of the executive team took it as par for the course."

• predictable
• typical
• usual
