How can I calculate benefit rates per paycheck instead of per pay period?

In the Communicated Rate Frequency field, select Estimated per pay period on the program basic details page. In the Value Passed to Payroll field, select Estimated per-pay-period amount on the standard rates page.

Scenario: Your payroll processes either weekly or biweekly, so some years you have 52 or 26 payroll runs and others you have 53 or 27. Regardless of the number of payroll runs, you always issue 52 or 26 paychecks per year. Also, you want to calculate the rate communicated to participants per those 52 or 26 paychecks.
