dc.descriptionGood tracking requires significant quintessence energy fraction, even in the past, but a potential that is not yet truly slow-rolling. The supernova bound on cosmic acceleration excludes constant equation of state and inverse power potentials, but allows the SUGRA potential and other good trackers, in which quintessence energy domination and kinetic energy suppression {\em both} began only recently. This makes the time in which we live special in {\em two} respects.
