Cuts are USA Swimming single-age motivational standards (B → AAAA) at age 10.
National cuts (Sectionals → Nationals) are the current-season meet qualifying times for the swimmer's zone and age group; ✓ marks the hardest cut already achieved.
Pool tags are a venue speed heuristic (median deviation of all swims there vs each swimmer's typical time) — see the venue page for the method.
