While in retirement the Total Income tab shows concurrent withdrawals from my IRAs as well as my taxable brokerage accounts. I was expecting to see withdrawal order: Taxable first, then withdrawals from tax advantaged. Doesn't it make sense to let tax deferred grow until taxable funds are completely depleted? I can withdraw funds from the tax advantaged accounts for several years to meet the estimated smooth consumption level. So, I do not understand the rationale for pulling from both concurrently.
