Okay, yeah, I get what your saying right, multiple outputs, means higher throughput, higher throughput means better factories, etc. But what I'm saying is that, the load and unload speed should change to match the speed of the conveyor(s) attached.
Like if you have a mk6 conveyor belt pulling out resources, then the unload speed should change to match that, 900 items/s. Or if you have a mk5 conveyor pushing in items, then its load speed should also change to match that, 780 items/s.
And if you have 2 outputs, each with, say, a mk6 conveyor, then the unload speed should change to 1800 items/s. Same thing for the input.
See what I'm saying?
