In addition to 300MB blocks, I have some entries in my usage record history with less than 300MB blocks. i.e: 168.34MB. If the system report in 300MB blocks how does it happen?

This happens in situations where the customer’s router enters in to a Power reset or reboot during usage. Router restart will trigger the system to send usage records to usage record history without waiting for a 300MB block to complete. This will indicate the usage details of the last session based on current records and not in complete 300MB blocks.
