Henry produced a handful of nice touches as the Pulse made light work of the Mystics to avenge a 69-68 overtime defeat in round five but they just looked a more composed lot with the Silver Fern on the court.
The win kept the Pulse's playoff aspirations alive and their run in to the post-season includes a home outing against the West Coast Fever on Sunday, home-and-away clashes with the Tactix and a trip to Invercargill to meet the Steel.
Broughton's side couldn't ask for an easier run to the finals but they will need to find an extra edge during the next month or so.
Too often they've given up games this year when they've had a lead and Henry, who has playoff experience from her previous stints with the Magic and the Mystics, said the elite sides don't do that.
"Playoff teams know how to win under pressure. I think we've been found wanting in those situations to date," the 30-year-old said.
"I think this is a step in the right direction but we have a lot more work to do."
The Pulse are in seventh place on the transtasman netball league ladder but are only one win outside the top four and Henry said there would be little margin for error in the coming weeks.
"We need to treat every game like it's our final and that's how we approached the game tonight. So that'll be our next test is looking at our next game, approaching that as a final."
Against the Mystics, the Pulse produced too many unforced errors but the 15-goal winning margin was important because it helped improve their points differential which took a pounding when the Vixens beat them by 22 goals in round seven.
Caitlin Thwaites (43/47) was busy at goal shoot for the Pulse, while veteran Donna Wilkins continued to provide a steady hand at goal attack and shot 20 from 22.
The Mystics only had themselves to blame as they committed 23 turnovers to the Pulse's 17 as they remained at the foot of the table.
