In this paper we report on the entry points leading to superdeformed (SD) as well as normal bands. We find that, compared to normal bands, the entry spins for the SD bands are about 9 {h bar} higher, and the entry excitation energy 1--3 MeV colder. We also conclude that population of the SD bands represents successful competition against fission. SD bands in both the Dy and Hg regions are considered.
