If we have two teams A against B, we estimate the chances for home win as follows:
1. Difference in the table between the two teams (negative if team A is below team B currently in the season table)
2. Household Indicator (team A)= the number of home wins (W) minus the number of equal matches (D) and lost matches (L) at home
3. Guest Indicator (team B)= the number of the guest wins (W) plus a number equals as guest (D) minus the number of lost meetings as guest (L)
4. General indicator of the host (team A) for the last 6 games (total home and away) as the points are:

-win at home with 1 goal difference: 1 point
-win at home with 2 goals difference: 3 points
-win at home with 3 and more than 3 goals difference: 6 points
-win as guest with 1 goal difference: 2 points
-win as guest with 2 goals difference: 5 points
-win as guest with 3 and more than 3 goals difference: 7 points
-equal at home: 0 points
-equal as guest: 1 point
-loss at home: -4 points (negative)
-loss as guest: -2 points (negative)
