Some comments on the timing
of WWR..
The yearbook (15.23-3) gives
allowable timing accuracy. This is because taking times to better than
the nearest second, with manual start and finish, only introduces an appearance
of accuracy. It is quite possible for one paddler to appear 0.1 sec faster,
when in fact it was just the finisher being 0.2 sec quicker in pressing
the button, and the real time was 0.1 slower. The conventional way to
do this has been to ignore all the digits which are not taken account
of, rather than to round up and down. This leads to fewer errors when
working things out in cold and wet conditions.
With a manual start, the
starter should give the signal as close as possible to the nominal time
(exactly on the minute) and this nominal time should be taken as the start.
It may appear more accurate for the starter to press a button when saying
"Go", but in fact this tests the starter's reactions more than the paddler's
speed. Some people may find it easier to give the countdown with a sweep
second hand than from a digital readout. In this case, both clocks must
be syncronised, and remain syncronised. Mechanical (sweep hand) stopwatches
can run quite badly out out of sync over only a short time - worrying
when they might be the main timing means for some races.
Bib numbers should match
the start time in minutes past the hour, if possible. This make it much
easier to cope with gaps in the start order where a competitor withdraws
from the race, etc.
If a beeping clock is used
for start, this takes out one human error (when to say "go") but it is
important that the paddler knows which beep to start on, and whether the
start or end of the beep is the time. The starter needs to be vigilant
to ensure that no paddler starts before the recognised time. Experience
with a beam about 6m after a beep start shows that there can be two seconds
difference in time to the beam, some of which is due to paddlers starting
to paddle at different times; not just acceleration.
More sophisticated timing
methods have more scope for error. Any results issued at the event should
be stated as provisional, and full checks should be made, using beam times
if available, on the times of all prizewinners and anyone else within
say 2 seconds of a prizewinner.
