All said and done, jubilant co-owner JP "Steak" Goodin took it a step further after MacDonald asked the deputy chairman of the Taranaki Thoroughbred Association to shed more light.
"You won't get that dividend again, believe me," Goodin said, adding it went some way to making up for the disappointment of losing the Ranfurly Shield to Waikato last week.
He revealed Saturday's race didn't go according to trainer Allan Sharrock's well-laid plans, but champion jockey Opie Bosson and Shez Sinsational kept their composure in the final leg of the Rush Munro's Hawke's Bay Spring Racing Carnival trilogy.
"It didn't run like Allan said it would run but he had confidence in the horse and Opie's on a roll."
Goodin said the plan was for the rider and horse to come a little closer much earlier in the 2040m premier race.
"But he [Bosson] knew the horse has a phenomenal switch, which she did in the Auckland Cup and here [Windsor Park Plate] two weeks ago."
Bosson was the first to accept he hadn't ridden Shez Sinsational right in the Windsor Plate.
So when they analysed the videotape everyone was happy.
Goodin lauded the organisers for their hospitality and sponsors for staging a great event.
"It's great for racing and we have some very new owners so it's all success-filled enthusiasm."
Shez Sinsational came into the Spring Classic having already pocketed $1.2 million for her owners before raking in Saturday's $187,500 plus the silverware.
"The trainer was, unusually, very confident.
"He had done his homework. The only other time he was this confident was in the Auckland Cup this year.
"The weather played up and the trainer had problems running in and towards the end of the time he got a bit shaky.
"This is the only other time I have known him to be so quietly confident and he's been my trainer for 30 years," Goodin said, adding the pundits had failed to realise how fast the horse came home here two weeks ago.
Shez Sinsational finished second last in the 1600m Windsor Park Plate on September 22 from the No 14 barrier.
"She came in quicker than the winner [Mufhasa] by half a second, which is three lengths."
Bosson, 32, of Pukekohe, said while he had his reservations with the mare, Sharrock never doubted her ability.
"She's much the same as Princess Coup who's won a couple of Kelts [now Spring Classic] as well so she has a similar type of rating and finish."
The No 14 barrier placed a handicap on Bosson and Shez Sinsational.
"That was difficult but we tried to cope because we didn't have enough speed so we came from behind and everything fell into place in the end," he said, adding he knew he had the premier race sewn up at about the 600m mark.
A winner of 42 Group 1 races, Bosson revealed he had weight issues coming from Singapore in mid-August.
"I had four weeks off from Singapore to New Zealand so I put on a little bit of weight," he said, adding he had loaded 5kg but food control, gym workouts and saunas helped chip away the kilos.
"I'm still getting it down now and it's been a good couple of months."
How much of Saturday's victory was the jockey or the horse?
A grinning Bosson replied: "She pretty much took me all the way around."
Serving a week's suspension, Bosson celebrated with a disciplined dinner and a couple of drinks.
