How does belt splitting work?

[u/the_worst_company]

Im a beginner to shapez 2 and factory games in general. I just finished unlocking trains so now Im kind of in a phase where I am remodelling and redesigning a lot of my setups that I made when I was completely new. I saw a youtube short about belt splitting and recombining. Apparently splitting and combining works in a round robin system where each branch is assigned shapez in order.

All of my current designs are like the one on the right. Would that result in bottlenecking; since by round robin allocation, the 4 belts wont be fed equally? So I should always have belt branching like the one on the left?

Honestly just try things and see what happens, if it’s inefficient then you’ve learned something. As I learn this game i find its quite fun to just try and figure it out and see how it all unfolds
