Rule group transition in RPAS

Hi,

I wanted to confirm my below understanding for rule group transitions for below condition.

Config guide says

On workbook building –

Data is loaded using the load rule group. This typically loads measures by calculating them from the data values held on the domain using the master modifier, but may also calculate other measures that are not explicitly loaded --- (how it works?).

When the load is complete, the system automatically executes a full transition to the calculate rule group.

On data refreshing –

Data gets loaded from DB for the domain by using master identifier.

If any measure gets changed by user, calculate rule group runs and then Data gets loaded from DB for the domain by using master identifier.(Am I right here?)
