Ignore this. I've updated the code to the complete 100% working (including preferred improvement types and counting # of improvements over 1), incase anyone else needs a value calculator 
Time to start working on the other item types. Yay. ). Some items that are improved have the correct value (#3). Others are way off (#4). I am wondering if any dfhack veterans have any suggestions.
