Points Prediction Tool
Calculate how many ladder points a win or a loss is worth.
Points prediction
Enter the points both teams hold before the match to see what a win or a loss would be worth. Only the outcome (win, loss, tie) matters. How the win is achieved (win by stars, loss by duration) doesnt matter.
Your expected score (win probability)50.0%
Opponent expected score: 50.0%
If you win
actual score = 1
You+18→ 1018
Opponent-17→ 983
If you lose
actual score = 0
You-17→ 983
Opponent+18→ 1018
How it is calculated
expected_score = 1 / (1 + 10^((opponent_points - your_points) / 800))
point_change = 35 * (actual_score - expected_score)
The change is based on the points both teams hold before the match. A win counts as an actual score of 1, a loss as 0. This is the standard Elo system used in many other sports, just with different constants.
Each team's change is rounded to a whole point, half up (15.5 → 16, −15.5 → −15), so a win and the matching loss need not cancel out exactly.
