Note: If the value in the table is negative, the mean wait for the Optimal Policy is less than the 3-bed Flex Track Policy (by the amount listed), if the value is positive, the mean wait time for the Optimal Policy is greater than the 3-bed Flex Track Policy (by the amount listed).
Note: If the value in the table is negative, the mean wait for the Optimal Policy is less than the Fast Track Policy (by the amount listed), if the value is positive, the mean wait time for the Optimal Policy is greater than the Fast Track Policy (by the amount listed).
