When comparing two methods to compute reorder points, the method that achieves the lower total pinball loss is the best one. Since the reorder point is nothing but a quantile forecast, it is possible to evaluate the accuracy of this forecast through the use of the pinball loss function. In practice, the reorder point error is typically reduced by more than 20% if any one of those three condition is satisfied. This improvement is mostly explained by the fact that the extrapolation used to turn a mean forecast into a quantile one becomes the weakest link of the calculation.
