Hand timing vs electronic timing in swimming.
What actually separates the two methods, which one wins when both are running, why there's no official conversion between them, and where phone timing sits.
In short
Electronic timing (touchpads or transponders) takes precedence over hand times whenever it's fitted and working, per Swimming Australia rule SW 11.1. There is no official conversion between a hand time and an electronic time in swimming, unlike athletics' well-known +0.24 second rule, so a hand time stands on its own rather than being adjusted. Phone-based timing, like EasyMeet, is still hand timing: a person taps the finish, the system just removes the start-reaction error and averages two timekeepers per lane.
Hand timing vs electronic timing, side by side.
| Hand timing | Electronic timing | |
|---|---|---|
| Who starts the clock | Each timekeeper, on the starting signal | The timing system, triggered by the starter |
| Who stops the clock | A timekeeper, the instant they see the touch | A touchpad or transponder, on physical contact |
| Precedence under SW 11.1 | Backup, used if electronic fails | Takes precedence when fitted |
| Equipment needed | Stopwatches (or phones) only | Touchpads, wiring, a console |
| Typical use | Club nights, time trials, school carnivals | Sanctioned meets, championships |
There is no +0.24 s rule in swimming.
Athletics has a widely known official conversion: add 0.24 seconds to a hand-timed sprint to estimate what an electronic time would have shown, to account for a timekeeper's reaction delay on the stop. People sometimes assume swimming has the same thing. It doesn't. There is no official Swimming Australia or World Aquatics conversion between a hand time and an electronic time in swimming.
The practical upshot: treat a hand time as a result in its own right, not as a rough estimate of an electronic time with a fixed offset applied. If you need to compare swimmers who were hand timed on different nights, compare them to each other, not to an assumed electronic equivalent.
Phone timing is hand timing, done carefully.
EasyMeet is not a touchpad system and doesn't claim to be. A timekeeper still watches the wall and taps their own phone screen the instant the swimmer touches, exactly the same action as pressing a stopwatch. What changes is everything around that tap: every phone in the meet receives the same synced GO signal from the server rather than each timekeeper reacting to the starter independently, and two phones per lane are automatically averaged into one time, with a lane flagged for a manual check if the two taps land too far apart.
Measured in our own tests: 240 clock checks over 4G, worst case about 0.022 s (0.009 s on home internet).
That figure is the system's own clock error, the gap between two phones agreeing on what instant "now" is, not the accuracy of a person's finger on the glass. A timekeeper's own reaction to seeing a touch is still the limiting factor in the final number, the same as it always was with a stopwatch. What the sync removes is the much bigger, much less consistent error of several timekeepers each reacting separately to the starter, which is where hand timing usually loses the most ground to an electronic system.
- Still hand timing: a person taps the finish, there is no touchpad
- The start is server-synced, removing timekeeper-to-timekeeper start variation
- Two timekeepers per lane are auto-averaged, same idea as SW 11.3's two-watch rule
Picking the right method for your meet.
Most clubs don't actually choose between hand timing and electronic timing in the abstract, they choose based on what a given meet needs and what's affordable. A weekly club night or a school house carnival rarely justifies hiring a touchpad system for an evening, the setup time alone can outlast the meet. A regional championship or a meet that feeds into a state qualifying pathway is a different story, where the extra precision and the acceptance of electronic times by the state body matter more than cost.
For everything in between, club nights, time trials, school carnivals, the question is really which hand timing method: a volunteer with a stopwatch and a paper card, or synced phones with auto-averaging. Both satisfy SW 11.3. The difference is consistency: phones remove the start-reaction variance between timekeepers and catch a mistimed tap by comparing it against a second phone on the same lane, which a lone stopwatch and card cannot do.
Hand timing questions
Which is more accurate, hand timing or electronic timing?
Electronic timing, run through touchpads or a transponder system, removes human reaction time from the finish, so it's the more precise method and takes precedence whenever it's fitted (SW 11.1). Hand timing depends on a timekeeper's own reaction to seeing the touch, which varies swimmer to swimmer and timekeeper to timekeeper.
Is there an official conversion between a hand time and an electronic time?
No. Athletics has a well-known +0.24 second conversion between hand and electronic sprint times, but swimming has no equivalent official conversion. Don't apply the athletics figure to a swim time, or invent your own, a hand time in swimming simply stands on its own rather than being adjusted to estimate what an electronic time would have been.
Is phone-based timing like EasyMeet hand timing or electronic timing?
Hand timing. A person still taps the finish on their phone the instant the swimmer touches, which is exactly what a timekeeper does with a stopwatch. What's different is the start: every phone receives the same synced GO signal from the server instead of each timekeeper reacting separately, and two phones per lane are automatically averaged. It's hand timing with the human error at the start removed and the finish-tap error averaged down, not a touchpad system.
Why would a club choose hand timing over hiring electronic equipment?
Cost and simplicity, mainly. Touchpad and transponder systems need wiring, consoles and setup time, and are usually hired in for a meet rather than owned by a small club. Hand timing, whether stopwatches or phones, needs nothing more than the timekeepers themselves, which is why it remains the standard for club nights, time trials and most school carnivals.
Do hand times count as official qualifying times?
They can be used for club records, handicaps, and tracking a swimmer's progress, but a time counting as a Swimming Australia sanctioned qualifying time depends on the meet being run under licensed officiating, separately from whether the timing method itself was hand or electronic.
