(1) The designated MIRO for a vehicle for a year is:
(a) if the MIRO number for the vehicle for the year is less than or equal to the lower breakpoint for the vehicle for the year--that lower breakpoint; or
(b) if the MIRO number for the vehicle for the year is between the lower breakpoint for the vehicle for the year and the upper breakpoint for the vehicle for the year--that MIRO number; or
(c) if the MIRO number for the vehicle for the year is greater than or equal to the upper breakpoint for the vehicle for the year--that upper breakpoint.
(2) The MIRO number for a vehicle for a year is the number of kilograms in the MIRO (mass in running order) that is entered on the RAV in relation to the vehicle at the start of the interim reconciliation day for the year.
Example: If the MIRO (mass in running order) that is entered on the RAV in relation to a vehicle at the start of the interim reconciliation day for a year is 2,150.3kg, then the MIRO number for the vehicle for the year is 2,150.3.
