Of the 36 runs combined between the 12 athletes in the final, only 15 were completed, and even then, some of the completed runs had issues with their landings. Only five of the 12 athletes were able to land a run resembling their best work and post a score of 80 points or higher, when nine were able to reach that mark in qualifying.
Pyatt said he was impressed with the way Porteous, 20, handled himself despite all the obstacles facing the athletes on the day.
"It was about negative 25 and windy, so it was very challenging. But it was no surprise that that could happen here. We knew this venue had that and we've been testing out different warm layers and different things just to make sure we could be the best prepared for today and he was able to stay warm and not be too surprised, so good on him. It takes a strong mental skiier to ski through that."
For Porteous, who went into the event as the favourite to take out the gold medal despite not having the top qualifying score, it was a matter of putting all of the hard work he had done into practice.
"It's been such a journey; an absolute journey. Full of highs and lows; it's been some of the times of my life and this just really caps it off," Porteous told Newstalk ZB.
"It's incredible and I'm still pinching myself to be honest; I really can't believe it."
