Wokers' Compensation Calculations

SOLVED

Does anyone happen to know the 'behind the scenes' math for the 5-3-2 Workers' Compensation table window? I need to know how to set it up for the most accurate job/employee costing. For example does the Liability column calculation run after the Employer % column calculates or is before? I've probably run 20 sample company payrolls to try and figure it out and just can't seem to crack the code! I will be using the Employer %, Liability, Exper Mod, and Add Exper Mod columns. If any one knows the specific details for these formulas, I would love to know too!
