Each group has a graphical display (‘Runtime’ button) that works in a similar way to the fill level of a grain silo.
The grain silo is naturally full at the start of the group, as the group functions completely free of charge for a certain period of time after the group is created.
The fill level of the silo decreases slightly with each calendar day.
As long as the silo is not empty, the group works without restrictions.
Each contribution payment automatically refills the ‘silo’ for all group members.
