The Perfectionist personality has a requirement where a dragon must have a growth time equal to or less than the minimum growth time for its species, with a two hour grace period. This means that an Angel Dragon would have to reach its hatchling stage within 76 hours in order to qualify for Perfectionist, as well as meet stat requirements. Some species will have a rather generous time limit, like Kirin (87 hours). But for some others, like Wings Dragon (55 hours), you will have to budget your time wisely! Using Adore or Cuddle can also help to keep a dragon's growth time low, as it can remove several hours worth of waiting and keep you ahead of the clock.
