For Rohan Browning, it's only a matter of time until he sets the legal sub-10 second mark that catapults him straight into the world 100m sprinting elite.
And he sees no reason why it can't happen as soon as this weekend's Australian Olympic trials.
"I know it's in my legs; I know that I'm in the best shape I've ever been in," the 23-year-old Sydneysider said.
"On the one hand it helps to get the right conditions, but you don't want to be dependent on that.
"I think it would be poetic to do it in Sydney.
"It would be such a great script if it were to happen, to win my first national title on my home track."
Browning has already dipped under the magical mark, when he clocked 9.96 with the aid of an illegal tailwind in Wollongong in January.
He also went agonisingly close to joining Patrick Johnson in the ultra-exclusive official Australian sub-10 club last month when he set a legal PB of 10.05 in Brisbane.
"The 10.05 is objectively the better run when you factor in the conditions and the data on it," Browning told AAP.
"But the 9.96 holds a special place in my heart because that's the threshold.
"Even the casual sports fan, or the non-sports fan, knows about the sub-10 second 100 metres.
"I've always though that to be a world-class competitor I have to be able to run under 10 seconds."
Having already bettered the brutally difficult qualifying standard of 10.05, Browning will guarantee himself a spot on the Tokyo Games team with victory on Saturday evening.
"I haven't lost a race this season and I don't plan on starting at the Australian Olympic trials," he said.
"The previous two seasons I've been completely undefeated on the domestic circuit and then lost the trials when it mattered.
"The biggest difference between years gone by and this year is that this is the first season where I've had an uninterrupted preparation and I've been able to string together a lot of races."
No Australian male sprinter has contested the blue-riband 100m at Olympic level since Josh Ross in 2004.
You have to go even further back to the 2000 Sydney Games for the last occasion when Australia had an active interest in both the men's and women's 100m events.
There's every chance that could be replicated in Tokyo, with late-blooming Hana Basic within a whisker of the qualifying mark of 11.15, having clocked 11.18 and 11.19 at last month's Queensland Track Classic.
"That just shows how tough the (women's) automatic qualifier is too," said Browning.
"There is definitely an air of excitement in the sport right now, beyond the sprints.
"People are feeling good about athletics again."
Basic is also unapologetically targetting Melissa Breen's seven-year-old national record of 11.11.
The semi-finals and finals of both 100m races are on Saturday evening at Sydney Olympic Park, with the trials wrapping up on Sunday.
Thirty-one athletes have already bettered the qualifying standards for Tokyo, including Australia's only reigning world champion, javelin thrower Kelsey-Lee Barber.
The final team for the rescheduled Tokyo Games is expected to number around 70 athletes.
