Copper 7200/min stable --- 4 to 5 MkIII belts + reaction speed optimized --- Tileable (perfect 1/20th - 1/16th - 1/12th - 1/10th of planet in the biggest 4 tropics)
Want to build a forgeworld? Consider this late-game, 4 to 5 MkIII belt, 1 to 1 smelter (Copper here, usable for Iron and Stone Brick aswell) optimized for fast reaction speed to full processing capacity. Perfectly tileable in all 25+ wide tropics, ILS set to local demand/supply + global storage. When used as building block for a forge world, you can fit 6x20 (equatorial band )+ 4x16 (next one) + 2x22 (smallest 2 bands) = 228 of these puppies neatly together, yielding a whopping 1.6416M items per minute of 1-to-1 smelting power.
