The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.
