What if what you're working on is going to take longer than 25 minutes, and then taking that 5 minute break breaks up your mental flow?

That is, after returning after 5 minutes it takes a couple minutes to re-orient yourself to the problem at hand?

For me, Pomodoro is a technique to help you get started, and to focus. Vs procrastinate all day.

For the case you mention, I would adapt the technique to whatever benefits you the most. If you're in the flow, defer the break. If you defer too much, and start feeling burned out, adjust.

For some people, 25 minutes is too long. Find what works for you.
