If I understand correctly, they are used for differently but rely on the same principle; using a time to delimitate a task (in this case, to delimitate reflexion time).
I was actually thinking on using org pomodoro for implementing this.
It's close enough. Half the benefit of pomodoro is training your brain to quantify the passage of time in reality, vs what it feels like in your head. Only then can you begin to reliaby estimate how long it'll take to do complete tasks.
