That seems pretty well covered by the article though. They explicitly say work for as long or as short a time as you are feeling good about. The only thing that's particularly rigid is that you have a fixed and rigid end time for the break based on how long you worked. It feels less like replacing feelings with ridiculously rigid schemes and more like a plan to actually listen to your feelings, but also have personal accountability to return to the task. It's real easy if you're the sort of person that struggles with procrastinating on tasks to "feel" like you're ready to get back to work.
