Elliptic flow at BNL RHIC is computed event by event with NeXSPheRIO. We show that when symmetry of the particle distribution in relation to the reaction plane is assumed, as usually done in the experimental extraction of elliptic flow, there is a disagreement between the true and reconstructed elliptic flows (15%-30% for {eta}=0, 30% for p{sub perpendicular}=0.5 GeV). We suggest a possible way to take into account the asymmetry and get good agreement between these elliptic flows.
