A wretched run of just one win in their last 12 top-flight games has seen Stoke slip to four points above the relegation zone going into a crunch clash at the Britannia Stadium on Saturday with an Aston Villa side occupying 18th place.
Pulis, though, believes two wins from the final seven matches is all that is needed to keep the Potters in the Premier League for a sixth consecutive season.
"I've heard managers talking of needing 39 points, 38 points, maybe even 37, but as far as I'm concerned 40 is our target," said Pulis.
"We've seven games, with 21 points available, to get the six we need to stay up, and we've four home games.
"The Britannia is a tough place to come to, and as long as we get the supporters behind us, then I'm sure we'll put in the performances to pick up the points."
Pulis, though, has dismissed captain Ryan Shawcross' suggestion the game with Villa is "season defining".
Pulis added: "Everybody wants to build it up because it is the next game, and then they will build up the next game and the next.
"The longer you go on without picking up the points then the pressure does start.
"But the important thing is the players go in with the right attitude and have the confidence and are relaxed enough to perform."
Pulis, however, does believe it is time for his players to stand up and be counted, although that little bit of luck he feels has been missing of late would not go amiss.
"You are judged as a person when things aren't going so well, and I have always thought when you are up against it, that's when you show what you are made of," said Pulis.
"I'm just hoping the players relax, go out there and play, and if we can play as well as we did against Everton, Newcastle and West Brom, and get a few breaks, then the result will come.
"Our problem is we just haven't been scoring goals because in general play we have played well, and competed well, this year.
"But the one thing our situation has brought home to everybody is that our league is relentless.
"It doesn't curry any favours to anybody, and we're no different to anybody else.
"You can take the top six or seven sides out of that, but for the rest of us, if you have a bad run, things don't go for you and you don't get the breaks, or you're not on it then you get punished.
"That is most probably why we are down there, because we haven't taken the chances we should have, and we can't keep doing that."
