So first off, here's my lane balancer. As far as I know this allows 100% throughput (just a bit big).
And here's what I'm calling a 2-Belt Overflow Balancer. It will keep the inputs on their output belt (top stays on top, bottom stays on bottom), and will only actually balance between the two if either are backed up.
And lastly, here's two lane balancers, followed by the overflow balancer:
Hey, I don't really understand how is your lane balancer better than this much simpler version? https://wiki.factorio.com/images/Lane_balancer_mechanics.png
I don't want to be rude, just genuinely curious if I am missing something here. Thanks!
I imagine if they play like me then they just prefer to use their own clunky designs :-)
I like getting to the end of a run and looking back on an empire of turds. My turds.
The one you've shown has a balanced output, but not a balanced input. It's possible on your linked version that when the output gets backed up, only one of the input lanes will get backed up.
Mine guarantees that the inputs are even loaded.
