I am turning a PCAP file from a '32E' sensor and storing it in a bag file for ROS1 and ROS2. When I bring these into MATLAB and read the messages from the bag file, many properties are the same but one major differences is that each VelodyneScan message has a different number of packets.

ROS2 has more packets in a given scan (all consistent sized) than the VelodyneScan from ROS1. Is this a difference that sure be occurring, I expect both ROS1 and ROS2 to have the same results / have the same number of packets from the bag file.
