> when you have finished a task, or got stuck -- you are breaking at precisely the point where it will be hardest to resume work.
This might make sense from a procrastination point of view, but my point is that you should stop there to revise your strategy so that it will be _easier_ to resume. But with pomorado you just have to grind through because your 20mins isn't up yet... To me that seems inefficient.
When I say stuck I don't mean a hard challenging or complex part, I mean you really are stuck and that's why you should stop, because you aren't making significant progress and it's inefficient. You don't necessarily need to give it deep thought like I suggested, sometimes simply having a break is enough to give you a fresh perspective once you go back.
Anyway, it's all subjective, not only to the individual but probably also the task.
