Sunderland boss Ricky Sbragia sees 41 points as being the benchmark for Premiership safety this season.
"I'm looking at about 41 points as a benchmark," he said.
"Obviously, I'd like as many as possible but 41 points is the minimum - that's what I think will as good as guarantee safety.
"There's a guy I know that uses computer software to predict these things and I asked him how many points he thought would be needed for safety.
"He said between 38 and 41, and he's usually not far wrong.
"I think we need four wins - if we get those, it's a tall order to ask the teams down at the bottom to take four more points than us in the last 10 games."
