Record of highest equipped item in a given slot?
 

So I had a wonder, and I can't seem to find the answer anywhere.

Just where in the hell does the game store the records of your highest equipped items for a slot?

They use the data to determine if a loot drop gained using personal loot is able to be traded away so it has to be somewhere right?

It does not appear to be stored in Lua.
