The way the performance metric is calculated might lead to the cancellation of trains that are late to avoid that they are included in the metric calculation on a given day. d. The way the performance metric is calculated might lead to more trains that arrive on-time. e. The way the performance metric is calculated might lead to the addition of trains to increase the denominator in the metric calculation
