Here's something to consider on a rainy day when you feel like exercising your brain a bit.

Except as it turns out, engaging in a more rapid series of smaller – but permanent – spending cuts can be even more effective. For example, rather than cutting spending by 20% for 3 years after a market decline, if the retiree simply commits to trimming real spending by 3% (permanently) in any year that market returns are negative – approximately the equivalent of forgoing an inflation adjustment during the down year, and a fairly trivial spending adjustment for most retirees – the safe withdrawal rate rises by almost 0.5% (to more than 4.5%). With the large-but-temporary cut, the safe withdrawal rate only rises by 0.1%, instead.
Of course, the flip side to this is that it may be equally appropriate to make upward adjustments in retirement spending once a retiree has the benefit of hindsight to inform their sustainable withdrawal rates in retirement. Particularly given the conservativeness of safe withdrawal rate methodologies (i.e., they are testing against the worst case scenarios experienced to date), there’s reason to believe that many retirees will get further into retirement and have an option to increase their spending, which can be implemented through spending policies such as the Guyton-Klinger withdrawal rate rules and a ratcheting safe withdrawal rate.
