"You do have to go in with the mental approach of being patient. It is unrealistic to think about winning stages 10-cars back on the road so it will almost be like a different rally - minimise the damage on Friday and then make the time back on Saturday."
Despite the event being run slightly earlier in the year than normal the conditions will still feature the traditional boggy stages and lack of grip beyond the first few cars although the rain is forecast to subside later in the weekend.
"It is always pretty similar here," the 30-year-old said. "We have seen in the recce wet, muddy conditions. I think the rain is supposed to ease as the week progresses but the roads will still be predominantly wet so it is going to be a pretty traditional Wales Rally GB."
Paddon will pilot one of four Hyundai i20s this weekend as the Korean manufacturer looks to try and keep both the drivers' and constructors' titles alive for the championship finale in Australia next month.
Four-time reigning world champion Sebastien Ogier holds a 37-point advantage over M-Sport Ford teammate Ott Tanak, while Hyundai's Thierry Neuville is a further point back in third. M-Sport leads the manufacturers' title with a nearly unassailable 83-point advantage over Hyundai.
"I think both championships are a foregone conclusion now anyway," Paddon said. "I think it is important for each individual driver and the team to finish these last two events on a high building towards last year.
"It is really about individual results, getting some information data and improving the car.
"I would like to put everything that has happened this year behind us and get a couple of good scores on the board to finish the year off."
