Standing tall by the pool deck is Cut, a long-legged crane in a referee's cap, a whistle round his neck and a slender horizontal bar he holds level as a ruler. Cut is the keeper of the qualifying cut — the time you must beat to earn your lane at the big meet. He is strict, but never unkind: the line is the same for everyone.
A young swimmer checked her time against the cut and got confused. "The cut is 1:10. I swam 1:12. But bigger numbers are usually better — did I make it?" Cut lowered his bar gently. "In swimming, remember, smaller time is faster," he said. "So the cut is a ceiling, not a floor. You qualify only if your time is less than or equal to the cut. Your 1:12 is bigger than 1:10 — which means slower — so it's just over the line, this time."
He wrote it as an inequality: your time ≤ 1:10 qualifies. "See the direction? At or under the line. 1:10 exactly? You're in. 1:09? Comfortably in. 1:11? Just out — by one second." He never made her feel bad about the near-miss. "Two seconds over isn't failure," he said. "It's a target. Now you know exactly how much to find."
Say it with Cut, out loud: "Your time must fall at or under the line — meet the cut, and the lane is thine."
She circled the cut, saw her gap, and trained straight at it — and a month later she touched the wall at 1:09. "Under the line!" she called. Cut gave a single crisp nod and raised his bar. "At or under qualifies. Welcome to the meet."
That is Cut's move. A qualifying cut is a threshold, and because a smaller time is faster, you qualify only when your time is less than or equal to the cut. Read the direction of the inequality carefully, measure your gap honestly, and aim right at the line.
