A method, a data aggregation tool, and a set of instructions are disclosed. A data storage 120 may store a data aggregation tree with at least one entry node, a root node, and an initial entry status level for the at least one entry node. A processor 110 may detect an entry node status level change to a resulting entry status level at the at least one entry node. The processor 110 may aggregate a root node score at a root node based on an entry node score for the at least one entry node.
