As a means to optimize TM maintenance, being able to generate a histogram of segment reuse would allow an informed and objective decision process for deleting TM content when reuse rate becomes negligible (ex. of all segments reused in 2016 projects: 50% came from 2015, 30% came from 2014, etc.. could lead to delete all content from a year when reuse rate drops below X%, or when reuse rate for 2 years in a row is below X%, the % being defined together with the client).
