Bromley has won all his sport's major titles but success at the Olympics has always eluded him.
He designed the sleds which took British sliders Alex Coomber to bronze in Salt Lake City and his partner Shelley Rudman to silver in Turin.
Nothing has been left to chance in Vancouver, with Bromley using a hydrometer to test track conditions in a bid to fine tune his sled.
"Understanding the weather conditions really could be the key here," he said.
"Most teams note the temperature but not with the same attention to detail that I do.
"You need three elements to be successful - firstly athletic skills, the push-start and driving ability.
"But you also need to pay attention to technology, without all three you won't stand a chance. In my view, it's 70 percent athlete, 20 percent start and ten percent technology on this track."
Bromley's results have been mixed this season, with just two visits to the World Cup podium.
He has been ranked consistently among the top eight in practice, although he insists he pays no attention to those standings, which appear to show home slider Jon Montgomery, a silver medallist four years ago, as the gold favourite.
"I'm still trying things out, we get six training runs and I'm testing options so the times are irrelevant," added Bromley.
"My season has all been about building my momentum to this point but I'm not trying to build anything else up, I'm treating this like a normal World Cup."
Bromley insists he has no fears about the safety of the track, despite the tragic death of Georgian luger Nodar Kumaritashvili during a training accident last week.
While partner Rudman insists she would never do anything that would jeopardise her safety - with their two-year old toddler daughter her main concern.
"Ella is my number one priority and I wouldn't do something that was absolutely high risk," she said.
"If there's been an accident on the road am I not going to drive my car any more? I'm here and I believe it is safe.
"I would always think of my own safety and what happened was very difficult for everybody. I did feel more at ease when I saw the changes made by the officials but I don't feel it is a dangerous track."
Meanwhile, Rudman's British rival, Amy Williams, looked impressive as training continued at the Whistler Sliding Centre.
Williams has made no secret of the fact her relationship with Rudman is strained - and has medal claims herself, after winning silver at last year's World Championships in Lake Placid.
Williams produced the second quickest time during the third women's training session - eclipsing home favourite Mellisa Hollingsworth, who finished joint fifth, while Rudman was ninth fastest.
