The number of Items in the Beam Dose Verification Control Point Sequence (300A,008C) is not required to be the same as in the Control Point Sequence (300A,0111). A different sampling can be chosen for the Beam Dose Verification Control Point Sequence, but where the Cumulative Meterset Weight of a Control Point Sequence (300A,008C) Item is the same it shall be referenced by the Referenced Control Point Index (300C,00F0).
