For goals that put the team in the lead, n is equal to the lead before the goal is scored. For goals that tie the game or see the team trailing, n is equal to the deficit after the goal. So for goals that:
Tie the game, or put the team up 1: n=0, and the goal is valued at 1
Cut the lead to 1, or put the team up 2: n=1 and the goal is valued at 0.8
Cut the lead to 2, or put the team up 3: n=2 and the goal is valued at 0.64
Cut the lead to 3, or put the team up 4: n=3 and the goal is valued at 0.512
And so on.
Thanks a lot for doing all this work.
What was your rationale for the values you assigned to the goals?
It seems like the chart creates a value for goals scored with extra wight for the importance. It may be interesting just to use it to dumb it down a bit and track percentage of a players goals that are tie-breaker goals or goals when the team is down or up a goal and divide that by the players total goals.
It may help us get a clearer idea, which players tend to contribute most when goals are needed the most.
