With just 10 games to go this season, the Magpies sit on 40 points, eight ahead of the bottom two in League Two.
Nolan says he is taking it a game at a time, with a tricky visit to table-topping Doncaster Rovers awaiting on Tuesday night.
But with Notts back on form, the manager is taking the opportunity to draw up more of a mid-term goal.
"We have gone with the attitude that we will try to get to 50 points as quickly as possible and then we will reassess when we get there," he told the Nottingham Post.
"But what we are looking at right now is three points and the next game.
"My plan is just about Doncaster and what we can do to make sure we give our team the best chance of beating them.
"Everyone says 50 is the safe mark in football but you just never know in football."
