Only a point divides the top two from third and fourth, and results this week will determine just where Saints, as well as Leeds, Wigan and Huddersfield, will end up.
“My head’s a mess at the minute – I don’t know where we’re going to end up!” said Makinson.
“I keep looking at the table, and there’s so many possible outcomes.
“We’re just going to put in the best performance we can and see where we end up.
“Then it’s play-off football.”
One team not involved in the shake-up for the semi-finals is Warrington, who Saints welcome to Langtree Park on Thursday evening.
The Wire have flattered to deceive this season, and finished the regular Super League season in sixth.
But Makinson expects them to be back in contention next season, after going through a transitional period.
“They’re a great side, and maybe they’re just going through a transitional period,” he said.
“They’re losing a few at the end of the year, and bringing a few more in.
“The competition’s that tight these days, and there’s that many good teams, that there’s been a few shocks this year, and there will be over the [coming] years.
“They’re a great side and they always will be, but I think they’ve been on the end of a few results this year that they didn’t expect.”
