Momentum
A live measure of which team is controlling the game at any point in time. Momentum is calculated by weighting every coded event (tries, carries, tackles, turnovers, territory entries, set pieces, infringements) and applying a time decay so recent events matter more than older ones. The result is a score from -100 to +100 that updates every minute: positive means the home team is in control, negative means the opposition. Key factors that drive momentum include collision dominance, tackle quality, territorial pressure, set piece success, and discipline.
