Possession
Introduction
When playing a match, the possession your team has at a certain minute determines your chances of getting a goal chance. It depends on both your team's and the opponent team's midfield.
Possesion can be observed on the match report, at the end of the first half (minute 45) and the end of the second half (minute 90). That number is calculated using a formula which takes on consideration the midfield level of both the teams at that particular minute.
Formula
Possession(your_team) = 100 * (Midfield_(your_team) / (Midfield_(your_team) + Midfield(opponents_team)) )
- The scale of the midfields values is: 1=disastrous (very low), 2=disastrous (low) ...
- You can test an implementation of the formula at The HattriX-Ray
Observation
One of the consequences of the formula (in terms of gameplay) is that, to get a certaing possesion, you need to beat your rival's team by a highest number of levels when the average midfield level is higher. For example:
- disastrous (very low) vs wretched (very low) (1 level) = 71% possession
- solid (very low) vs 'excellent (very low) (1 level) = 54%
Also, the midfield values used in the formula are the ones on that particular minute, while the midfield rating that is displayed at the end of the match is the average of the midfield during the 90 minutes. This explains the cases where discrepancies between the possession percentages at the 45th and 90th minute and the midfield rating seem to appear. Events such as:
- red cards (to players affecting the midfield)
- injuries (to players affecting the midfield)
- weather non-goal events (to players affecting the midfield)
- confusion
- overconfidence
- Team attitude
- Playing Counter attack
- affect the midfield, hence affecting the possession as well.
