The Kirkpatrick thing is being discussed: Evaluating various withdrawal strategies
I cannot tell what's going on in it because it is poorly written, so any conclusions are dubious to me. I can write that the method that produced the best results suffered from the thing that Kitces was writing about.
Also, any study that only does rebalancing on an annual date is worthless to me. There are better ways to pick the dates to rebalance than 12/31 or your birthday each year.
