Clarification Needed on Preliminary Calc, Final Calc, and Automatic Paysheet Update

Our organization routinely experiences new errors between our last regular calc where the Preliminary Calculation Run checkbox is still checked, and when we run our first "final calc" where Preliminary Calculation Run is not checked. Our organization has configured Pay Groups to have the Automatic Paysheet Update flag turned off. We think the errors are caused by changes to Job Data made between the last regular calc and the first final calc.

We need better clarification as what is passed to Paysheets when the Automatic Paysheet Update flag is turned off, and either before or after a final calc has been run. Our expectation was that Automatic Paysheet Update being off would stop Job Data updates from affecting Paysheets mid-payroll.
