How the score works
- Every tracked move is weighted by significance (high / medium / low).
- Weights decay with age — a move loses half its value after twelve months.
- Breadth across move types and named vendors adds to the score.
- Scores are scaled so the most active firm sits at 100.
- Trend compares the last six months against the six before it.
