Pomodoro does the opposite effect for me. Very often a task needs 20 minutes or 35 minutes. It jerks me out of flow by sticking to a forced 25 minute schedule.

There are some boring, tedious work like writing documentation and tests, where the Pomodoro Technique works well. But not for truly deep work.

25 minutes interval is recommended but you always can change the interval to longer to suit yourself.
