Slots: athletes from the age group who qualified (before any rolldown). Last slot: the slowest qualifier's finish time and age-group place, then its adjusted (age-graded) time. *Needed: the finish time that equals the pool's adjusted cutoff for that age group (cutoff ÷ age-group multiplier) — any faster finish earned a slot. Age-group winners qualify whatever their time.
