Very few players knew the cooking system very well and *almost* nobody had any way of calculating results to any degree of accuracy. In fact, i doubt anyone at SV really knows the cooking/alchemy systems very well and/or how/why they work. Its a relic left over from Mats' old design days and one he never finished, so far as i know. It really shows in the types/values of new materials that have been added over the years... one op ingredient after the other, theres no balance in it.
SV has a chance to fix this... someone can take up the 'game designer' hat and truly understand the design Mats had in mind for this and either adjust it to give more materials more purpose or revamp it to make something altogether different.
more towards the OP now, it would make more sense for this kind of thing to happen using the 'combine' skill rather than cooking, just due to nature of how 'ingredients' and 'completed foods' are considered.

i understand that the value were a bit of a mystery still but i highly disagree that "very few" ppl knew the cooking system well. the guide "cooking for the masses" gave the values of certain foods and based on similar ingredients you could gauge the other ingredient's values relative to pig or wtv.
like density relative to steel for crafting guides. everywhere i went in mo1 ppl knew cooking and had pretty good knowledge of it too. cooking is one of those skills where everyone learns it... but no one realy puts time into it.
the alchemical skill, that i can understand... i tried to learn it but gave up halfway..
