Actually size consistency is the only improventent of quadratic methods
over classic configuration interaction methods. This is achieved including
some higher order excitation terms (quadratic in the expansion
coefficients). You might think of it as a simplification of the e^-T
expansion which retains size consistency in a coupled cluster calculation.
