From a conversation with supersrdjan:
"Intervals for incremental writing should be wave-like. At first they grow as you elaborate. Then they compress as you consolidate. And when it hits bottom you either publish the article, or if you're not there yet, another cycle of increasing interval for further elaboration starts.
The problem with ever-increasing intervals is that it encourages you to start elaborating on new ideas at the expense of consolidating old ones. I know Naess recommends manual intervals but that's just, you know, a solution for lack of a better one.
You know, I think it's applicable for tasks to. It reminds me of Sebastian Marshall's Terminator mode. The more a task nears completion, the more resistance you feel toward actually completing it. So, wave-like increments could help there too.
Well, after a certain inflection point, the increments start getting shorter, to encourage you to wrap things up.
Ah okay. Well the equivalent of my idea would be that, at first, making progress on a task decreases its priority. This leaves room for you to step back and evaluate a little bit. Try other things. And then after a certain point it starts increasing the priority, to either conclude or dismiss the task. I guess this would only make sense for a particular type of task."
