Wrexham director Shaun Harvey says the club's season can be considered a success whatever happens this weekend.
The Red Dragons occupy the last remaining play-off berth ahead of the final round of matches, where they host fourth-placed Middlesbrough on Saturday.
While Harvey claims if they do achieve a fourth promotion in a row it would be the "greatest sports story ever", he would not want missing out on a play-off place to be deemed a failure.
"The time is now. We've got one game to go of the league season," Harvey said.
"To use [Manchester United managerial legend] Alex Ferguson's favourite phrase, it definitely is 'squeaky bum time'. Will we make it or won't we make it? Well, there's a story to be written either way.
"Because whatever happens, we've gone from being a non-league team to the best team in Wales by virtue of league position.
"We've finished in our highest league position ever and the women's team have won the [Adran Premier] league and will compete in the Champions League."

Goal difference alone separates Wrexham from seventh-placed Hull, with Derby still able to leapfrog both sides on the final day.
The club have only failed to gain promotion once in Ryan Reynolds and Rob Mac's time in charge of the club, when they missed out on the National League play-offs during their first season at the helm in 2021.
Since the appointment of current manager Phil Parkinson, Wrexham have secured an unprecedented three successive promotions and now target an historic fourth.
"In all circumstances, our season should be viewed as 'we nearly made it', rather than 'we just missed out'," continued Harvey.
"And whilst that's a subtle difference, the reality is we have no right to actually achieve what we have done so far this season.
"If we do make it to the play-offs on Saturday afternoon, we have the chance of going back-to-back-to-back-to-back promotions.
"If we achieve that, as others have said and I agree, it would be the greatest sports story ever.
"As it happens, it's authentic, and that's what makes Wrexham so relatable to many others who care to dream."
