How far have you progressed with each campaign? The final mission, even on NM, will award a statue for the Honor monument. Even one statue will net you another two points for your goal.
If you've completed all three campaigns, that's three, which puts you near the Five Statue award. If you've completed any Guardian tracks or are close, that's more statues.
One statue will award you 2 points
Five statues will award you another 3 points
Linked account will award you 3 points
