@HamptonWizard Hi!
Whenever I ask Alpharetta similar questions I’m told the GO data is the most recent data available.
If you have a subscription and have access to ‘year’ and ‘yearR’ for the same year, the ‘yearR’ is the most recent data, and the ‘year’ data would be the most recent before the release of the ‘yearR’ data.
I hope that helps,
Jeremy
