To finish first, first you have to finish — and that has proven the case for the championship's top three in 2022.
For the second season running, Shane van Gisbergen could win the title with a 100 per cent finish rate.
Only van Gisbergen and Waters have completed all race laps through 12 rounds.
It's no surprise, then, that they occupy first and second in the drivers' standings.
Chaz Mostert is third on the list and third in the championship, and has only dropped three laps in 2022.
It came six months ago in Tasmania, when Mostert was an innocent victim in someone else's collision.
Mostert was trailing Mark Winterbottom and David Reynolds when they collided in the Symmons Plains opener.
Will Davison and Anton De Pasquale both have more podiums than Mostert, but DNFs have affected their seasons.
Davison and De Pasquale are 118 and 140 points behind Mostert respectively.
De Pasquale crashed out of the first Pukekohe Sunday race after a collision with Brodie Kostecki.
Davison, meanwhile, crashed out late in last month's Repco Bathurst 1000 while sitting in the top 10.
Adelaide, which has a high attrition rate, will put the series leaders' finish rate to the test.
Just six drivers — van Gisbergen, Waters, Mostert, Brodie Kostecki, Mark Winterbottom and Chris Pither — have finished all 32 races.
Waters was inches away from disaster in the Saturday Gold Coast race when he hit the chicane barrier and spun.
He kept his Monster Ford out of the concrete walls, and came home fifth.
Three drivers recorded their first DNFs of the season last weekend, and they all came in the same accident.
Broc Feeney, Todd Hazelwood and Lee Holdsworth all retired after being caught up in the lap 4 chicane crash.
It has been a bruising season, with 2022 setting a new record for most red-flagged races in a season.
Six races have been suspended this year due to crashes; as revealed by V8 Sleuth, that surpasses the previous record of five in 1997.
Scott Pye has been involved in two of them, and has had a torrid season when it comes to crashes.
Pye was wiped out in Perth and Darwin, with both accidents triggering red flags.
Jack Le Brocq triggered the first red flag in Tasmania, and clashed with Pye in Perth.
Thomas Randle has suffered a season-high six DNFs, ahead of Pye, Le Brocq and Andre Heimgartner.
Drivers will complete dual 78-lap races in Adelaide to round out the 2022 Repco Supercars Championship.
