Trying to feed a Hungry Node and I've already created 69,089 Crafting Tables in a Deep Storage Chest. How many do I need to get all the Primal Aspects to 500 oe enen 1000?
The larger it gets, the more it needs
Very much this. The higher the aspect count it is, the less likely it is to actually improve the node. It's also very much down to chance. You could very well feed it 6k crafting tables and get 1k in each aspect. The chances of this happening are astronomically low though, and also discounts any aspects the node already has.
The chance is even two fold as well, it's a bit like feeding the item to a deconstruction table, and taking the resulting primal and attempting to add that to the node. Additionally if this is for energisation, you get diminishing returns on the CV/t out as well. To get 5 cv/t you only need 25 vis capacity in the node. To get 10 cv/t you need 100 vis capacity. (This also assumes a normal node, bright and pale nodes get a 20% bonus or penalty respectively).
The formula needed is square rooting the capacity of the node for each primal, applying the bright or pale modifier, then flooring the result. If there are compond aspects in the node, the compounds count for each of the primals in the compound (for example if a node contains Lux, the lux would count for both Ignis and Aer.) The catch is only the highest count for each primal counts. So A hypothetical 26 lux, 38 aer node would give 5 ignis cv/t and 6 aer cv/t when energised.
EDIT: There is no magic number as in 10k crafting tables to get 500 of each aspect, or any reliable formula. It's down to that double chance factor.
