Effective dates Used for Benefit Deduction Calculations

I had a hard time finding what dates are considered by Payroll processes for Benefit Deduction Calculation. With the aid of google search results, Peoplebooks and spending some time I formed the below list of tables along with the dates that are used in each of these tables for Benefits deduction calculations in Benefits Administration, Payroll and Payroll Interface. I request PeopleSoft consultants to correct me if I am wrong in specifying any of these. Thanks in advance.
