Our main result is that the complexity of computing linear projections of an equidimensional, but non necessarily reduced, curve (or equivalently the degree-complexity of the Grobner basis computation for elimination orders) has its maximal value, namely Bayer’s bound mo, if and only if the smallest linear subspace containing C is a plane. If this is so, mo coincides with the degree of C and with the degree-complexity of the reverse lexicographic ordering.
