Why is SSJ3 shown as tiring to maintain, but SSJ4 is not?


In several episodes of DB:Z and DB:GT, using SSJ3 form is shown to be _very_
tiring for the user and burns up energy very quickly, compared to
SSJ1/2/enhanced/mystic/etc.

However, when DB:GT rolls around, SSJ4 form, while as tiring as all other
enhanced forms, doesn't seem to put as much strain on the user, nor does it
have a time limit, as with SSJ3.

Is there a distinct reason for this in terms of power drain, or how the body
handles the transformation, or is this perhaps something overlooked when GT
was created?




Don't forget that GT is a filler, it wasn't created by the original creator,
**[Akira Toriyama](http://en.wikipedia.org/wiki/Akira_Toriyama)**.

There is a very high probability that is was overlooked. Also if I remember
correctly, SSJ3 wasn't shown as tiresome in Dragon Ball GT.
