It is instant if you decide to start a level 1 Class (or Level 30 HW Job) on Floor 51 (instantly level 60, huzzah). Hell, even if you start on Floor 1, you're still levelling up rapidly fast and chances are the party is not going to wait for you to read your tool tips (presuming players read them at all). I've already encountered a BLM who didn't know their basic level 40 rotation at Floor 81-90.
