Posh boss Dave Robertson believes five wins from the last seven League One matches would clinch a place in the play-offs.
Posh are currently ninth in the League One table, but just one point away from the final play-off place going into the busy Easter programme.
Robertson reckons 71 points would secure a top-six slot.
Posh face two Easter games against relegation-threatened teams that are struggling for form. They travel to Scunthorpe tomorrow (Good Friday) before hosting Walsall on Easter Monday.
Posh dropped out of the play-off places last weekend after losing 1-0 at the ABAX Stadium to Coventry - a first home defeat since Robertson became first-team manager.
“I’ve discussed our targets for the rest of the season with the players,” Robertson revealed. “And I reckon five wins from the last seven games would get us into the play-offs.
“It’s a tough ask, but we have just completed a run of five wins in seven matches so we know it can be done.
“And if we go into the play-offs on the back of 10 wins in 14 matches we would probably be the team to beat.
“It’s important to go into the play-offs with momentum and we would have plenty.
“There is a long way to go before we get to that stage though.
“The two games over Easter won’t decide where we finish, but they are obviously very important.
“Everyone has six points to play for in a short space of time and the league table could look very different early next week.
“We must make sure that we are one of the teams moving upwards and I am confident we can make it happen.
“We had a setback last weekend when we didn’t play well, but we were stll unlucky to lose.”
