Focus Planning FAQ
Should I always use 25/5 focus intervals?
No. Try shorter intervals for high-friction tasks and longer intervals for deep technical work.
Why add a planning buffer?
Buffer protects schedules from interruption, rework, and setup overhead that pure estimates miss.
What is meeting load cost?
It is the direct meeting time plus transition costs before and after each meeting.
