Fremantle coach Ross Lyon will leave his calculator at home as the Dockers prepare themselves for a mathematical and physical test against AFL strugglers Melbourne on Saturday night.
The Dockers could finish as high as sixth - and earn a home final - or as low as eighth depending on a myriad of results this weekend.
Fremantle are expected to thrash lowly Melbourne in Perth, but the final margin will play a large role in determining where the Dockers finish.
If Sydney beat Geelong, Fremantle (with a percentage of 112.4) will finish sixth if they can ensure their percentage ends up being higher than the Cats (116.0) and North Melbourne (111.6).
Because Geelong and North Melbourne (who take on Greater Western Sydney) play their respective games before the Dockers, Fremantle will know exactly what they need to win by before their game against Melbourne.
But Lyon claims he couldn't care less about all the different scenarios, saying it would be fraught with danger if his team started worrying about percentage instead of the win.
"I won't bring the calculator. I failed quantitative studies at uni, so it's not a concern for me," Lyon said on Thursday.
"Potential results are a distraction.
"All I know is if you muck around with your form, if you take your eye off the ball and you blink, you've lost to a bottom-of-the-ladder team.
"I can certainly see the headlines if we were to lose on the weekend.
"I'd prefer not to see those headlines, but we've got a fair idea of what they'd look like.
"So we're pretty determined to continue to write our own story, and our own story is prepare really well, improve our football and respect our opposition and don't worry about future possibilities."
Lyon also dismissed suggestions Fremantle would be better off finishing eighth if cross-town rivals West Coast finished fifth, a scenario that would set up a western derby final and cancel out the Eagles' home-ground advantage.
Fremantle skipper Matthew Pavlich, who has been struggling with Achilles tendon tightness and a corked hamstring, will be given up until game day to prove his fitness.
Lyon revealed the club had flown in tendon experts to assess Pavlich's niggles in recent weeks, but the 30-year-old was confident he could front up against the Demons.
"That Achilles he's managed for the last five years," Lyon said.
"We have a strong plan in place with that and then he had the adductor and corked hamstring.
"Most of that's settled down."
