Fun fact: The exact selling/fusing priority for cores is found by the sum of a core's cost per energy and sell value per energy. The higher the sum the better it is to sell that core. In comparison with other cores with a lower sum.

Obvious proof: Let's say we have cores a and b. We want to sell one and fuse the other. Let Ca and Cb be the cost per energy to fuse a and b respectively. Let Sa and Sb be the sell value per energy of a and b respectively. Intuitively we know that the higher Ca and Sa is the better it would be to sell it, so if their sum is greater than b's, we should. But lets go ahead and prove it.

We want to compare cases. When will we have spent the least amount of credits? If we sell a and fuse b, or the other way around? It is pretty clear, that if Ca - Sb > Cb - Sa, then sell a and fuse b. Cb - Sa will be the credits spent at the end of that proccess.

Ca - Sb > Cb - Sa <=> Ca +Sa > Cb + Sb

IMO: The section 'Sell vs. Fuse' has a misleading title. From that title you would expect an analysis of how many cores you farm vs duplicates, same polarity and different polarity mods to the ones you want to rank up. And if with these drops, their respective fuse costs per energy and other uses of credits it is better to fuse cores or sell them all in general. This analysis doesn't even overlap with the contents of the section. The title should be 'Which cores to sell (if you have to)' or 'Core selling/fusing priority' or sth like that.

Also, I don't understand how they made a table in that section with sell values and costs per energy, but failed to realise the simple truth that their sum is all you need for the selling priority. Especially when that whole setion leads to that and is essentially devoted to that point. If you're going to sell some mods and fuse some other, it is pretty obvious that with each sell you gain(sell value) and keep(fusing cost) credits, so the sum is obvious too. Your purpose for every mod in the inventory is either sell or fuse.

Idk, I may be missing sth here only having started the game...
