OM+ ELO FOOTBALL RANKING (METHOD 2)
The distinctive character of this second ranking method is that wins will have a greater impact respect draws or defeats. It simulates the 3-1-0 points system predominant in the modern football. Teams with an high number of wins are most rewarded, expecially those with good performances in the main competitions.
For this particular character the system is not a zero-sum, and indeed the total number of points in the system will increase constantly.
The particular values used to calculate the actual result have these effects:
-the system is not a zero-sum, and indeed the total number of points in the system will increase constantly;
-the winner team of a game always achieve positive points. These points could be trascurable if the win is against a very weak team but great if the win is against an high-ranked team, expecially for wins obtained in main competitions;
-a losing team could gain points in case of a defeat with a low margin, against a considerable better ranked team.

DETAILED EXPLANATION

1.1 - The Elo formula:

P = Pbefore + I *(W - We)

- P: points after the match;
- W: results of the match. The actual result of the match is assigned by a table showed below, based on the goal difference achieved (or suffered in the case of a defeat);
- Pbefore: points of the team before the match;
- I: importance of the match (values are listed below);
- We: win expectancy (1 / (10^(-dr/400 + 1))

dr = Pbefore of Team A - Pbefore of Team B+V
- Pbefore of Team A - Pbefore of Team B: difference in rating between the two teams involved, before the match;
- V: venue of the match is equal to -50 for the team playing at home, +50 for the team playing away, or 0 for the both the teams if they play on neutral ground.

Table for the actual results based on the goal difference:
wins:
+1 = 1,00
+2 = 1,05
+3 = 1,10
+4 = 1,15
+5 = 1,20
+6 = 1,25
+7 = 1,30
+8 = 1,35
+9 = 1,40
+10 = 1,45
+11, +12, +13... = +0,05 for each goal more

defeats:
-1 = 0,25
-2 = 0,20
-3 = 0,15
-4 = 0,10
-5 = 0,05
-6 = 0,00
-7 = -0,05
-8 = -0,10
-9 = -0,15
-10 = -0,20
-11, -12, -13... = -0,05 for each goal less

draws:
+/-0 = 0,5

2.1 - Rule for matches ended at extra-times or penalty shoot-out: this is applied only when the game is played in a single-leg: W=0,75 for the winner, 0,50 for the loser. But in two-legged games, only the results achieved after the regular times must be considered.

2.2 - Results taken into account
In the calculation, all the games are included between senior national teams full members of one of the six continental confederations (UEFA, CONMEBOL, CONCACAF, CAF, AFC, OFC). In general, are excluded from the ranking all the unaffiliated representatives that are inactives for many years and for which the nationality of the players is not verified by a superior governance. Only the games between teams labelled as "A" selection by the respective national FA are included in the calculation..

As general principle, the results achieved on the pitch will be used for the ranking, and awarded results will be not taken into account.
