hello all,
i have been checking the pics and vids from my london tri last saturday and just noticed that the time showing on the huge digital clock above the finish line the second i am crossing it has a discrepancy with my recorded time of 23-24secs (my recorded time is by that much longer)
does anybody know how this works? do they take the time that shows on your chip when they remove it from your ankle?
i am not in a position to be challenging any world records with this but 24 seconds are 24 seconds...!
cheers

It happens and in my case not disastrous but as you say 24 seconds is 24 seconds.
what you mention about the start raises another issue for me (pls forgive me, my first one so not very familiar with how it is all recorded...):
how do they register your time at the swim start? is it if you start say at 12:00 o'clock they start all the chips at 12:00 or is there a sensor in the water that logs the exact moment you literally cross the start line?
do you think i can dispute it with the organisers or is it too late?
it was time of day...my wave was meant to start at 5:00 and i am seen at the vid crossing the finish line at 18:54:41-2 and my recorded time is: 01:55:07
i am really bad at calculations number but if the hooter had gone later then i should have a shorter time not a longer one ...no? or am i getting this wrong
as you can see by my above question i am not clear from which point they start timing you either...i started at the back of the pack too ...
Obviously that doesn't happen with a triathlon so the master clock is manually synchronised with the klaxon, i.e. loud noise start button pressed - or countdown sequence initiated on master clock and starter given a 3-2-1 make loud noise.
Now if the clock you are referring to is showing actual time as opposed to elapsed time then it has all the usefulness as a sun dial! Just because the off is scheduled for 17:00hrs doesn't mean that you actually set of at that time, the last event I did we were 32mins late! So I conclude that your chip time was probably right and ignore the big clock.
i'd agree with zacnici - the chip seems more reliable than the clock, they could have held you in the water for 20secs at the start and you'd never know.
in te meanwhile i will settle for my 523rd position trying to imagine what it could be like to be 519th....
