On the recipes window the cost, profit, and profit per sec are all based on if you are selling the ingredients instead of making the recipe. It would be nice to know the cost, profit, and profit per sec if you are buying the ingredients from the markets. I know this only affects items, but it would be useful.
Those values are silly tbh. I've never found them useful in any way. There are useful values on the Recipe Stats page, which are: Can Make, In Progress & Techs Needed. And really it's just Techs Needed. The Cost/Profit/Profit per sec fields have potential but miss the point by comparing the cost of selling instead of buying the ingredients. This would only be useful if you had a surplus of the ingredients (rarely happens) and couldn't decide whether to sell them or to craft something with them. But in reality, we're buying ingredients to craft items to sell them and make money. So we still end up having to do math to ascertain best profit.
In fact some update seems to have broken recipes such that only a handful are even profitable at all. Ignoring early items, the list is: twine, glass, rivets, bolts, structs, boiling flasks, explosive bolts. That's it ... everything else like ceramics, diode, fuse, resistor, magnet, circuit, etc ... all of these require ingredients that are more expensive than their sale price. So crafting them only makes sense if you have a surplus of the ingredients (rarely happens) or you craft the ingredients themselves, which means you're both micromanaging the process and are probably better off just crafting something that makes a straight profit.
Random aside chuckle ... ceramics require Welding Rods to make. Not sure what universe this game takes place in where Welding Rods would be required to make Ceramics. lol.
