I had a moment of boredom at work and haven't seen anything the like until now so i decided to abuse a class diagram ...
this is a tree like thingy to show, which engineers do what upgrades and how to access them. Data is from inara.cz, red boxed are the max grade versions. Attributes are supposed to be requirements (meeting and donation), methods are supposed to be available upgrades with max rank.
Hope it is of some use,
