If the term of 3 year extension is correct, that is basically 81 points per season. He'd probably have to get another season in the high 80's or a low 90's so that knocks down what he'd need in the final year to low 70's. Then the 2nd and 3rd year, if one can be in the mid 80's it drops year 3 down a bit to under 80.
But, that also requires good health. Last couple of times he's missed big chunks of the year were in 21/22 for 13 games and about 30 before covid shut things down in 19/20 season.
So, if he missed say 20 or so games over these next 4, he probably doesn't surpass Jagr for #2.
