Friday night's running of the Moir Stakes, the $500,000 Group 1, will be the first edition Buffering hasn't been involved in since 2011 - when it was a $300,000 Group 2.
The lineage you can draw through Buffering's long, high-flying career and affiliation with the Moonee Valley sprint has a beauty about it - the two most recent Buffering-less Moirs were won by Black Caviar in 2010-11, and the one prior to that? Apache Cat.
While Black Caviar's name sits without equal in racing history, and Apache Cat was an out-and-out champion in his own right, the fact remains Buffering's mere presence in the Moir five years running - including three victories in it - has also been integral to its status boost.
Manikato won it in 1982, and Schillaci 10 years later, but only since 2013 has it earned Group 1 status - and while it has hard to determine how much of an influence, it is undeniable Buffering has been a part of it.
The race has graduated to be a Friday night feature, the showpiece of the opening of The Valley's night racing period - and no longer a Cox Plate curtain-raiser.
In recent years, Moir week would see Victorians show their inner Queenslander like it was State of Origin time in the NRL, and why wouldn't we? In the four Moirs from 2012-15, Mick Price's gun mare Samaready was the only horse to beat Buffering in it.
Even in his final crack in the race last year - when his best was assumed to be behind him and coming off that tough run in Hong Kong earlier in the year - he still started in single-figures and finished 3.2 lengths behind Extreme Choice, before having his racetrack farewell in the Manikato Stakes three weeks later when he was just as brave behind Rebel Dane.
So how is trainer Rob Heathcote feeling about what will be the first Moir he misses in six years?
"I just said to Michelle, my farrier, Buffering more or less had become part of your life," Heathcote reflected.
"Every spring for basically the last seven years, I've spent in Melbourne, backwards and forwards to Brisbane. My life as a trainer revolved around Buffering.

"Obviously I have a business here in Brisbane, but he gave me holidays every year because not only the Melbourne Spring Carnival - which is the best carnival on the planet - there was also Perth, and ultimately Hong Kong, and the success in Dubai.
"And I miss all that," he added with a laugh.
These days, Buffering splits his time between Living Legends in Melbourne, and co-owner Bruce Harry's place in Brisbane - and is enjoying the latter rather than lining up for another Moir - as he approaches his 10th birthday on November 5.
"Buff's actually at the owner's property in Brisbane, he's not at Living Legends this spring," Heathcote said.
"So he's up here in Queensland, and he's enjoying the sun on his back.
"The owner throws a saddle on him now and then, and gives him a trot and canter through the woods, chasing koalas, so Buff's pretty happy."
Asked if he felt a race re-name could take place for the Moir to honour Buffering's three wins in it, Heathcote was ever the diplomat.
"They've done that here in Queensland - they've named a bar after him, they're erecting a statue here at Eagle Farm in his honour, and they've named a race the 'Buffering Quality', which is a lead-up to the Magic Millions," he said.
"If they were to ever to do something at Moonee Valley [it'd be great], but it's not like there's not a shortage of champions to go around at The Valley, eh?"

Finding 'the next Buffering' is the prospect facing Heathcote, but the trainer's content with how things are tracking almost 12 months since the 'Buffering era' officially came to a close.
"It's never easy [finding the next one]. I've certainly had plenty of time to reflect on the wonderful journey he took us on, because it was the ride of a lifetime, and it's what any trainer and/or owner wishes for in this caper.
"I've got 56 horses in work here at Eagle Farm, so it's not like I'm bored. So it's still pretty busy, and it'll stay that way.
"Personally my stable's going well; we've had another good start to the season.
"I just miss the fact I don't have one that I can throw on an aeroplane and come down and enjoy the Spring Carnival."
And when it comes to champion regeneration, Heathcote is pretty confident he hasn't exactly found it in Buffering's little half-brother, Downloading.
"He has [got a lot to live up to], and I don't know if he ever will because he's a cheating, low down mongrel!" Heathcote said with a chuckle.
"He won a jumpout this morning, but if you stop riding him, he'll stop.
"He's so the opposite of Buffering, it's not funny.
"If ever you needed an example of Dawn Fraser's sister couldn't swim, in racing, that's it!"
And while Heathcote's unlikely to head south in the spring with his top-rater Hopfgarten, on Friday night he can sit back and watch the Moir stress-free and reflect on the influence his champion had on the race.
