	The main depolarization factors in the multi-step spin-transfer polarization technique and basic limitations on maximum polarization in the different OPPIS (Optically-Pumped Polarized H- Ion Source) schemes will be discussed. Detailed studies of polarization losses in the RHIC OPPIS and the source parameters optimization resulted in the OPPIS polarization increase to 86?1.5 %. This contributed to AGS and RHIC polarization increase to 65-70%.
