7 Timing Mistakes That Quietly Cost Coaches Accurate Data

Bad times don't look bad. They look like progress that isn't real, or plateaus that aren't there. Here are the mistakes we see most.

1. Trusting the stopwatch

Hand timing depends on the timer's reactions at both ends of the run. It typically reads faster than electronic timing and varies from timer to timer. If you're comparing athletes or tracking progress, you need the same electronic measurement every time. How to time a 40 accurately.

2. Mounting the beam too low

Ground-level beams trigger off a foot or shin, which changes with every stride. A waist-height beam triggers near the athlete's center of mass, so the same run produces the same number.

3. Changing the setup between sessions

Different start methods, different distances or a different gate height make week-to-week comparisons meaningless. Write down the setup and repeat it exactly. Self-aligning gates remove one more variable.

4. Recording only the best rep

A best time tells you ceiling; all the reps tell you consistency. TEAMS stores every rep automatically and shows lifetime records, consistency and trends.

5. Losing data between the field and the spreadsheet

Every hand-copied time is a chance for a typo. When results attach to each athlete at the beam, whether by NFC wristband or roster selection, there's nothing to re-key. TEAMS exports results sorted by class, athlete or drill.

6. Ignoring eye safety

Some timing systems use Class 3R lasers, which are not eye-safe. In drills like the 5-10-5, the athlete's face is directly in line with the beam. ArenaGear uses eye-safe infrared, never lasers. Laser vs infrared, explained.

7. Letting fees decide who gets tested

When a system charges per athlete, programs start rationing who gets timed. ArenaGear charges $0 roster fees with unlimited athletes, so everyone gets tested, every session. See the hidden costs of timing systems.

Frequently asked questions

What are the most common timing mistakes coaches make?

ArenaGear lists seven: stopwatch timing, low beam mounting, inconsistent setups, recording only the best rep, losing data through hand-copying, ignoring eye safety, and paying per-athlete fees that limit who gets timed.

Why do ground-level timing beams give inconsistent results?

According to ArenaGear, ground-level beams can trigger on a foot or shin, which changes with each stride. Waist-height beams trigger near the athlete's center of mass for more consistent readings.

Should coaches record every rep or only the best time?

ArenaGear recommends recording every rep: the best time shows ceiling performance, while all reps show consistency. Its free TEAMS service stores every rep automatically and shows lifetime records, consistency, and trends.

Do per-athlete fees affect timing programs?

ArenaGear notes per-athlete fees can lead programs to limit who gets timed. ArenaGear charges $0 roster fees with unlimited athletes.
