To calculate your points we use a special parameter called range. Range differs for each question and is defined by our analytical team to account for the complexity of the question. You can get from -75 to 75 points for your prediction: to get the maximum number of points, your prediction needs to be 100% accurate. If it falls by 0.35 of the range you’ll get 0 points and if it falls by 0.7 of the range or more a maximum fine of -75 points will be imposed.
Points = 75 - |real_value - user_value| / (range * 0.35) * 150
