How Duration is calculated/displayed doesn’t make sense to me. See these two examples:
Perhaps after a year it starts displaying in years not weeks, but the “1 year” is misleading because it’s more like 1.5 years.
In general, each of Duration and Time Remaining should have the option to choose the units (weeks, months, years, for example). The current approach, whatever exactly it is, could also be an option, but I and a client today both believe the inflexibility here is very unfortunate and not really up to the level of an enterprise product, and for the reason in #1, not a good default either.
