They definitely help me stay on track. I usually spend the 25 minutes on a hyper focus activity that I get lost in and could spend hours on, and the 5 minutes on a painful task like cooking where I wouldn’t know where to start and wouldn’t begin spontaneously (the 25 minute gap gives me time to plan what to do next, and the 5 minutes of manual work gives me time to check I didn’t get sidetracked on the main task)
