Using our standard SPADL representation, the estimated chance of scoring a goal from a shot is indeed always 0 or 1 as the result of the shot is already included in the representation. However, this is correct. To get to the actual VAEP value of the shot, you need to subtract the value of the gamestate before the shot: V(a_i) = V(S_i) – V(S_{i-1}). V(S_{i-1}) is roughly the xG value of the shot and it's estimation does not include any information about the shot's outcome. V(S_i) is the shot's result. Hence, VAEP captures the actual value above expected for shots.
