How to read the numbers
The main number is how much more an option wins than the most picked one in similar games. Those are games with the same draft odds (for items, the same game state and minute), played on the same patch by players with as much experience. A +2.0% means about two more wins per 100 games. Numbers from few games are pulled toward what the option does on other champions.
± is the marginMargin (±)The real number is very likely inside this range. More games make it narrower.. The real difference is very likely inside it. On the bar, the dot is the number and the band is the margin. The black line means no difference.
Better or Worse means the whole margin is on one side of zero and the difference is at least half a point. Even means we know the two are within a point of each other. Unclear means it could go either way. With Not enough games, there are too few games to say anything yet.
vs expected (WPA) asks whether games with the option ended better than their win chance when it was chosen. It doesn’t compare options with each other. Next to it is the win chance it’s usually taken at.
