Support fleet arrival is also RNG-based. It's entirely possible for them not to show up at all. The support fleet automatically returns at end of sortie regardless of whether they made it to battle or not.

This, BTW, is why many post-Ironbottom Kancolle-doujin (and even the official Fubuki Ganbarimasu manga) focus on the shenanigans of the support fleet and how they more often than not get lost on the way and must find their way back into the battle area by doing crazy hijinks.
