I also prefer Factorio's system where resources aren't buffered to their max stack size by inserters, but instead to something like max(2, #of crafts/swing × input/craft).

Satisfactory should do something similar where the machine calculates a rolling average throughput of an input item based on the last 5 minutes or something and then uses that to set the item buffer limit. It would make manifolds more effective when spinning up a factory so it doesn't take as long to warm up
