tracking plan results

What are your recommendations for tracking progress vs plan?

I have established a detailed plan and I am now starting into retirement. I am not sure how to easily review my plan against actual results when the plan is based on current dollars and real return but a year or 6 months from now my account balances reflect inflation and the nominal rate of return. I basically want to track and adjust my spending / consumption if market conditions fall short of my nominal rate of return (5% pa).
