It’s an extremely underrated way to do things, putting in the least amount of effort possible to fulfill the technical requirements of the task. It actually increases efficiency, because having completed one thing, you’re now free to move onto the next thing. Say for example you set yourself the goal of writing one sentence each day. You could try to use that one sentence to say something important, but saying something important might make writing that one sentence take an awful lot of time. If however instead you allowed yourself to simply write what came, you could finish that sentence in no time at all. Freeing you up to write multiple sentences that in the end meant nothing at all. And a lot of sentences, no matter what they say, look a lot more impressive than a single one. Especially if you weren’t planning on reading them back again anyways.
