Ratio
The following shows the minimum ratio of assemblers/machines and items required to produce chemical science packs such that all number of assemblers/machines are whole numbers. Items per min is calculated using assembling machine 3 with no modules or beacons and all assemblers running at full speed. The crafting of some intermediate products are not shown (due to the assumption that these items are available in large quantities within the factory). This table was produced using normal recipe difficulty.
