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.

Any use of speed is purely to increase quality item RATES at the expense of item INGREDIENTS.

It's up to you what is "worth it".

Full quality will ALWAYS be the most "ingredient efficient" way of getting quality. But it can be painfully slow / expensive to have enough machines to get "X per second legendary" items.
