Now consider that while Munro's international T20 strike rate is 153.33 (he's faced only 210 bal1s so is not in the accompanying table), Williamson actually has a higher rate than Guptill, Ross Taylor and Grant Elliott of New Zealand's leading batsmen in the T20 squad.
It simply proves there's more than one way to be a highly effective T20 batsman.
So while Guptill and Munro blast long and hard, Williamson is more likely to drive, cut, glance, nurdle and bunt his runs, but still at a merry clip. Call it different strokes.
"My role is to play my game," Williamson said yesterday.
"The way Guptill's going, it's brilliant. I need to adapt to make sure our partnership is doing what the team requires. That's what it's about."
Williamson knows his role may change from game-to-game.
Some days it will be about feeding as much strike as possible to his partner; on others it may be to take on some of the responsibility of finding, and clearing, the boundary more often himself.
Pakistan will present different challenges to New Zealand's batsmen in the three T20s which start their tour, beginning at Eden Park tomorrow night.
"We're going to sit down and have a look at their bowlers - make sure we scout appropriately," Williamson said.
"We'll come up with some plans for certain players, which we think is important.
"We still maintain that if we focus on our skills and play our best cricket, that holds us in good stead. [But] we'll look to do our homework."
And Williamson reiterated there's no concerns about the lack of opportunities for the middle and lower order batsmen so far this season in the T20s.
"That's a good problem to have. They are all very experienced.
"From our perspective it's been a good thing.
"We've played some good cricket and come out on top. When they get the opportunity they will be ready," said Williamson.
