So, today, 12-14h task X, after that "task Y" until 16h, then "cook lunch, eat" util 17h. It's 14:00, I just need to recompile X, make a .deb and upload it to a test server... 20 minutes max, and the others in the team can then test stuff and do their jobs... do I stop X and continue tomorrow, while everyone waits? Do I shrink Y to acommodate the lost time? where do I add "editing calendar" tasks? 5 minute slots between full hours? I'll stay with to-do lists.
