Camilla Lees and Daya Wiffen, who played a majority of the game at wing attack and centre respectively, combined for six of those turnovers, while shooters Caitlin Thwaites and Paul Griffin coughed up the ball nine times between them.
The Pulse have begun their campaign with two wins and two losses, while the Mystics are third on the ANZ Championship ladder with three victories and one defeat.
That defeat came last weekend after they were toppled 50-48 by the Adelaide Thunderbirds in Auckland.
The Pulse have failed to knock over the Mystics in nine previous attempts, although they have taken the Auckland-based side to overtime twice. The Pulse have also never won consecutive games in the transtasman league.
Broughton said past history, facts and figures weren't a motivating factor for her side.
"No, I don't think of it that way. I just think of each game as one that's there for us and we've got to play our best and do our best. We've got good players there, we just need to be careful of possession. It's a cherished thing and we've got to do things with it and we are good enough to."
Mystics coach Debbie Fuller said her side hadn't taken any notice of the statistics, either.
"We talked a lot this week about not being distracted by media, by the peripheral things," she said. "Distractions like that take away our focus from what we've got to do and that's putting quality netball out on court. We don't look into the history or get pleasure out of statistics like that. We get pleasure out of playing great netball."
The Mystics represent a stern test for the ever-improving Pulse and the most intriguing match-up outside of the midcourt battle will be the Pulse's tough defence against the slick Mystics shooters.
Katrina Grant and Te Huinga Reo Selby-Rickit have claimed 18 intercepts during the first four rounds of the competition, while Mystics goal shoot Cathrine Latu has drained an impeccable 93 goals from 96 attempts this year.
Latu doesn't need to look far for quality back-up, with Silver Ferns goal attack Maria Tutaia partnering her in the shooting circle.
Sunday's game gets underway at 7.40pm.
