Yeah, gap propagation on priority output of a splitter, when at least one full belt of input is present, is the exact problem that I meant.

Your balancing is not correct, that is why the gaps appear. Here is a no-gap solution, with a balancer from the book raynquist compiled some time ago Thanks for the example solution. I am sure that many other balancers work perfectly, but my goal was minimizing entities and optimizing performance i...

My approach is to create 5 nearly full belts and merge 1 of them into the other four to reach compression. The image shows a reduced representation where the belts A, B, C and D r...
