One additional caveat, the last Centaur burn does not necessarily circularize the orbit. For some geostationary transfer orbits, the Atlas V uses a multi-burn profile to place the payload into a geostationary transfer orbit with a high perigee and apogee at the geostationary altitude. See e.g. the CLIO launch (https://www.ulalaunch.com/docs/default-source/news-items/av_clio_mob.pdf) with S/C sep 2h52m after launch.
