Elo Rating will be changing for v4.2.8


It's now much simpler, just using the formula:

Rating Change = K-factor * ( Result – Expected Result )

Result being substitute by 1 for win, 0.5 for draw or 0 for loss.

Expected Result Table - based on current ranks of players/teams
Rating Difference | Stronger Player | Weaker Player
0 0.50 0.50
25 0.53 0.47
50 0.57 0.43
100 0.64 0.36
150 0.70 0.30
200 0.76 0.24
250 0.81 0.19
300 0.85 0.15

The Elo Rating Calculator will also be updated to use the new formula so that users can see how their score will be affected by different results.
