That fact is worth a pause.
There are records and then there are records.
The late Tommy Smith broke records set by everyone else, no one broke his - until now.
Smith was so dominant in Sydney racing he won the Sydney trainers' premiership a staggering 33 years straight until one of the finest trainers Australia has produced, Brian Mayfield Smith, toppled him.
Remarkably for someone who has achieved the heights so young, Waller is never flamboyant and is excruciatingly humble.
That is almost unknown in a town like Sydney, where glitz, glamour and hype in sport and racing are unrivalled. You're only as good as your last win and the bigger that win the bigger you are.
In Waller's case his achievements have been so enormous his response to it, or apparent lack of it, borders on annoying.
"I'm no genius, I've just got a good system that works," Waller said typically when Oompa Loompa and his friend Nash Rawiller scored early on Saturday's programme at Rosehill to provide Waller record-breaking win No 156 for the season
Tommy Smith, even if privately, always considered himself a genius and few argued.
Waller appears to be on his own in not considering himself a genius.
The New Zealander's only concession to real feelings are the tears he sometimes produces when being interviewed on television. That might not suit everyone, but without them many might consider racing's most humble participant almost heartless.
It probably wasn't a close call, but dairy farming could have captured a young Waller.
He was given the option of staying with the core family interest in farming in Manawatu or going racing and it's difficult to ever imagine he's regretted the way he jumped.
One of Waller's closest friends, Cambridge trainer Shaune Ritchie, who originally left for Sydney with his mate, says Waller's great asset is his ability to plan meticulously. To place his horses in exactly the right races, rather than something close.
Waller didn't disagree as he spoke to the Herald yesterday in a manner so quiet it was hardly fitting of someone who is the toast of the town.
He said that has come at the cost of not being able to spend the time he would like with his wife Steph, his two young children and his friends.
"But no matter where I am in Australia on a Saturday race meeting, I make sure I am home that night so I can get up early on a Sunday morning and spend the entire day with the family.
"From this point I will be attempting to spend a little more time with the family. It's some-thing that a lot of people in many walks of life have to contend with."
Waller is always focused and he says that's easy.
"We have up to 12 horses each racing for A$85,000 ($100,000) in nine or 10 races each Saturday, so you are racing for a million dollars on each of those days - it's not difficult to pay attention. Every Saturday is a group one raceday.
"And, fortunately, that gets attention in Australia, which is where I've been lucky." Most people wouldn't call that luck.
Like almost all great racehorse trainers, including Sir Henry Cecil, Bart Cummings and the like, Waller listens to his gut feelings.
"Probably one of my assets is that I keep an open mind, I don't like getting set in my ways or being opinionated.
"I've found I get results doing what my instincts tell me, rather than doing what others expect you to do."
Waller takes nothing for granted and in his own way is privately extremely grateful for each win.
"This is not an easy game. We got close to the record then the Saturday meeting last week was rained out. It was fortunate they could re-schedule it for the Monday and we got a couple of wins.
"We went to Rosehill on Saturday hoping to get the one win to break the record and we got four.
"It looks easy, but it's not."
Nothing prevents him from turning his phones off at 6.00pm.
If he could suddenly take six months off (yeah right) what would he do? "I'd see as much of the world as I could, both inside of racing and away from it.
"I like seeing how others do things.
"It's a big world and you never stop learning."
That from a man who sits atop the world's proudest horse racing nation.
