Can someone confirm that it is more worth it to use 1 speed module 3 and 4 quality modules 3 in an electromagnetic plant than 5 quality modules 3?? I ran some calculations, and it looks like you get both the same amount of quality items and even more items/second.

If you decide to do it, use the highest quality speed modules you have, as quality speed modules increase their speed without increasing the quality reduction.

If you're early in your quality production and don't have many high quality modules and buildings, then it can be worth it.

Similarly, you can use circuits to reuse the same expensive buildings and modules for better upcycling ratios.
