I guess we have different understanding of L24/N24. There is no need for a task to take 1 day, it can span days easily. I had tasks which spanned a week or two just because they were deep technical work. But I was able to explain what I did and what progress did I make to the room of engineers. Nobody has been asking me about deadlines or when would it be done, it's not that type of meeting. But it's a nice check-in point to see if I(or the team) move in the right direction and if I don't report meaningful progress for multiple days maybe I need help or extra eyes on my work. I would post draft PR with the code so other people can evaluate and correct my approach. This saves you from working days in the wrong direction.
