>>44134619Dragon Ball Z Kakarot tried to explain this by saying that a Saiyan's tail stops growing back if their human form becomes stronger than their Great Ape form.
But that makes no sense either because Great Ape is a 10x multiplier. Whatever your base power level is, your Great Ape form will always be 10 times stronger than that. It only becomes obsolete when Super Saiyan is unlocked since Super Saiyan's multiplier is bigger.
