Martin Guptill admits he has no idea how the Duckworth Lewis system works but conceded it worked to New Zealand's advantage at Eden Park yesterday.
A rain delay, and rejigging of the target from 81 in 87 balls, with five wickets standing, to 53 in 45 deliveries, made life easier for the hosts to wrap up a 2-0 series win, even if they needed just about every ball to get across the line.
"It did make it a little bit easier for us," Guptill, whose 82 won him man of the match, said.
"But I've got no idea how Duckworth Lewis works. We get told what we've got to chase, and I'm sure a few umpires around the world don't either. Sometimes it goes our way, sometimes it doesn't.
"Luckily we were ahead of the D/L when the rain came, so that helped us out a bit."
