Our prediction before kickoff

We had Leverkusen 66% to win, 21% for a draw, Union Berlin 13%. Leverkusen won: the pick was right. The final margin was 2.7 goals from ours; 7% of matches like this end further from the forecast than that.

Most of the distance between a forecast and a final score is luck: even with both clubs’ strength known exactly, a few shots decide a soccer match. This match was played before our forecasts went live, so this one was made afterwards, the same way, from only what was known before kickoff. How our predictions have done

About these numbers
