Level 0.3 / Level 0.5 Data
Level 0.3 and Level 0.5 data are very similar. One could say that the Level 0.3 data is a temporary, best effort set of Level 0.5 data based on what is available at the time of computation.
In theory, after N days the Level 0.3 data will disappear from a given date and a person will only view the Level 0.5 data.
