Reserve is carried from day to day. Each day keeps 80% of the day before and adds a fifth of today's target, built from your sleep (half), recovery (30%) and how light the day was (20%), minus anything stress costs above 50. It moves slowly on purpose, so one bad night dents it and a run of them drains it.
