WPA (ΔW) is the average change in win probability during an item’s time in your build, estimated by a calibrated win-probability model and averaged over similar game states. A positive WPA means the item raised win probability on average. Initial win prob (W̄) shows selection bias: values above 50% mean the item tends to be bought when already ahead.
