Have Splitters split each "lane" of a beltHave splitters split each "lane" of a belt more evenly when content is same on both lanes.
"But splitters already split contents" you say? You're correct, but it has a quirk.
If the input belt is fully loaded, it essentially takes the output and splits one lane to output belt 1 left-side and the other lane to output belt 2 right-side (may switch depending on circumstances). An example:
What ?If belt content is the same on both sides, still treat it as separate inputs (so technically a splitter would have 4 inputs -- belt 1-lane 1, belt 1-lane 2, belt 2-lane 1, belt 2-lane 2) so the output belt lanes are load-balanced more evenly.
So as shown in the rudimentary diagram below (and image above), the behavior of the Current System sees it's fully loaded with iron plate and says "a" is the first piece so to output track 1. "1" is second piece so output track 2, "b" is piece 3 so output track 1, etc:
the single input belt's contents are handled on a "per lane", per belt basis.
