I am trying to get a good main bus setup going. Can someone please link or list the ratios of different assembling machines for the various science packs? For instance, my understanding is that 3 assemblers doing copper wire can feed 2 assemblers doing green chips. Does anyone know good or optimal ratios for other items, such as inserter assemblers and transport belt assemblers for science packs 2? Blue science pack info would also be welcome, as would any other good ratios for any other common products.
Ideally, I am looking for the different numbers for different assemblers (grey, blue, yellow) as well as speed boosts .. but anything you have would be helpful

Thanks!
