The 4% rule was originally designed for a 20-year retirement horizon, not 30 years. For early retirees, a 3.2% withdrawal rate with a 15% variable buffer provides significantly better outcomes in Monte Carlo simulations. For more on this topic, see Small Business Retirement Plans.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.
