With reference to 'waiting times' being added etc, I am not sure that they were noted. I timed my overall time as being 16.05 and that is the time that I have been allocated on the results - although there was around 5 - 7 minutes or so waiting at Cray while groups were sorted out.
Not fussed though as it was a cracking day out - I just need to run faster next time!! Although I can understand the frustration it can cause.
