In the decade since City were last in the top flight, the average number of points amassed by the team finishing in the second automatic promotion spot in the Championship is 85.
Pearson's men currently top the table with 74 points - 13 points ahead of third-placed Derby with 13 matches remaining.
But the Leicester boss insists that what was good enough in previous campaigns will not get his side over the line this time around.
"In my humble opinion, I don't think that will not be enough this year for second place," said Pearson.
"I look at permutations and I keep being reminded of, historically, what has happened, which is fine.
"You have to look at it over a decent period of time, and that would be six to eight years. But, ultimately, you have to live very much in the moment. That is what we are trying to do.
"We have got ourselves in a very good position with 13 games left. We want to win every game we play. Whether we will or not remains to be seen.
"That will be the plan from here on in, that is what we will try to do, which is what we have done every game so far, and not try to hit a points target which would coincide with the kind of questions people want to ask right now. They are irrelevant."
