Did Toei go over-board?

With the whole "Saiyans get stronger the more they fight" concept.

Goku SSj4 (Limits Surpassed) >>> Syn Shenron >>> Goku SSj4 (Shadow Dragons) =/= Goku SSj4 (S17 Arc) >>> Goku SSj (S17 Arc) =/= Goku SSj4 (Baby Arc)

 

[SSJ2]

Yes. For example Goku went from his SSJ3 form being outmatched by Base Baby Vegeta to having his SSJ form surpass at least Super Baby Vegeta 2 in a matter of days (?).

 

[Six Trails]

Months.

 

[SSJ2]

Doesn't change how ridiculous it is.

The Black Star DB arc is also bad for it. Goku never really gets challenged in battle, yet he makes monstrous gains for no reason.
