So for latest/best/full:
Full: the full dataset with two time coordinates: runtime and forecast time.
This is all of the Grib data available in a single virtual dataset.
Best: the "best timeseries" of the collection dataset, one time coordinate
Latest: the most recent single model run
This poster is a good way to visualize the difference between Full and Best:
Using any one of those provides direct access methods without the need to scan
through the catalog to match a date string.
Hope that helps,
