Task: Question Generation
Input (English): Passage: Stanley Cup champions The outcome of the 2004–05 NHL lockout led to the shrinking of the payroll to $26 million. The Hurricanes, however, turned out to be one of the NHLs biggest surprises, turning in the best season in the franchises 34-year history. They finished the regular season with a 52–22–8 record and 112 points, shattering the previous franchise records of 94 points (in the WHA) set by the 1972–73 Whalers and 93 points (in the NHL) set in 1986–87 NHL season. It was the first time ever that the franchise had passed the 50-win and 100-point plateaus. The 112-point figure was good for fourth overall in the league, easily their highest overall finish as an NHL team (tied with the third-overall Dallas Stars in points, but with one fewer win than the Stars) and second in the East (one point behind the Ottawa Senators). The Hurricanes also ran away with their third Southeast Division title, finishing 20 points ahead of the Tampa Bay Lightning. Attendance increased from 2003–04, averaging just under 15,600 per game, and the team made a profit for the first time since the move from Hartford.
Output (English): How many years did the Hurricanes attendance  increase averaging 15,600 per game?
