One project of mine this last spring was tracking loot from elemental chests, titan kills, and those 5-kill titan chests. I’m not of a mind to invest the same amount of time into gaining game knowledge now as I was back then… but you might find the data useful… even tho it is pre-titan-parts.
This is the original thread, which contains a link to the raw data set, as well, should that be of interest.
