In Mindustry, you use conveyor belts to transport your materials around the map. You can eventually construct Titanium Conveyor Belts, which move items faster while the item is on that piece of the belt.
However, as each piece of material is a physical object to other materials, and existing material can block new material from entering the belt, so they can be compacted together to remove excess space, does it matter if I upgrade my entire conveyor belt line or can I get away with just upgrading the entry-points?
Since items are only blocked from moving onto the belt when entering it perpendicularly, you can theoretically smash as many items into a belt that you want (so long as it's not coming from a perpendicular direction). Doing so essentially creates an "opening" as the material gets pushed further into the line, allowing space for new material to enter the belt from a perpendicular entry belt.
So, the question is, is there a point in upgrading the entire line, or does cramming my unupgraded belts work just as well?
