Did I begin this bus right?

[MicFac]

I bought the game about 6 weeks ago and I started a new world a few days ago. This is the first world where I used multiple belts of resources from the beginning of the game. I wanted to know if I used all of the splitters right and if I built everything correctly so that it can have a high throughput. So here is a picture of my bus:

Looks OK to me.

I would say 4 belts each of copper and iron is overkill at this early stage of the game.

You are better to use 2 belts each and leave space for more should you require them later - as once you have access to bots you may decide to go for more bot-based builds, rather than continue to use belts, particularly if you have space issues.
