Any Profession Disclose Crafting Xp Formula

Basically, I'm trying to come up with a balanced cost formula for my crafted item disassembly idea, shameless plug: https://forums.wynncraft.com/threads/crafted-item-disassembly-2.261395/

It would be really useful to know the formula used for calculating the xp given by a craft, which I assume is based on the level and tier of the mats, level and tier of the ingredients, and possibly the level that the item rolls as. I think that this is useful information to know in general, and if staff thinks that revealing the formula would bring to light some exploit, then obviously the formula needs to be changed. Overall I think its harmless information to reveal.
