Does the 2N-2 candidate split planes for N primitives comes from possibly splitting the plane to the left and right of each of the N primitives, and removing two since the right of the right-most primitive is the same as the left of the left most primitive (and both cases are trivial, since there isn't really a split)?

Can we store the cost of calculate a object, so we don't need to calculate it again when we calculate a new costs of a partition?
