How does the chart work?
The movement of the chart indicates one or another team advantage ⚽ as well as the probability of winning in the end. At the beginning of the match the chart starts at 0 and from there it can move within a wide range of positive and negative values. The farther it strays away from 0, the closer one of the teams is to victory.
💁 Example: if one team intercepts the ball, then the chart will move in their favor a bit. Every event has its weight and affects the chart accordingly.
