If you think of it like nascar, a big elliptical ring with a camber pushing the cars to the center as they go round. So your arms are the road and any time the center point is not on the road, the staff will start to go off plane. Center point to the outside, it falls to the outside, center point to the inside it falls to the inside.
So to correct a bad plane you need to get the center point off your arm as it's going around the track of your arms, to the opposite side that the staff is leaning towards. Like if it's falling to the outside, you need to get the center point off center to the inside, underneath the 'high' side of the staff.
Mostly thou: Practise.
Or: just correct it with your hands when you get to that point.
