Yes, Staffing Requirement in Genesys Cloud is calculated based on Volume, AHT, Shrinkage, and SL Goal.
If you change the SL Goal Template in your Planning Group, it will affect the required staffing - but you need to re-run Forecast and Requirement calculations to apply the changes.
Make sure each Planning Group has the correct SL Goal linked, especially if you're working with different SLAs.
