Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error. For more on this topic, see Qualified Opportunity Zones.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period. For more on this topic, see House Hacking.

Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts. For more on this topic, see Index Fund Investing.

Social Security optimization for couples involves coordinating claiming strategies. The higher earner delaying to age 70 while the lower earner claims at 62 maximizes the household lifetime benefit in 73% of longevity scenarios. For more on this topic, see Insurance Optimization.

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