Distributions quote of the week
The difficulty to know how long the trip through NEW [package queue] will take has a significant psychological impact. Close to my home, there is a railway crossing on a relatively busy track. If the barriers come down, it can mean a wait time from a minute (a single train) up to 20(!) minutes (with several and/or long trains in close succession). This does not happen very often, but you have no way of knowing in advance. Thus, people take significant detours to avoid that level crossing, as they'd rather add five minutes for certain to their trip than roll the dice for an unlucky quarter hour.
