Something's been really bugging me while watching the pursuits - the clock doesn't stop when the leading team goes over the (thin, white) start/finish line but when they've just gone out of shot.
Towards the end of the womens' pursuit there was a wide shot as GB were catching up with the USA and the clock stopped when GB went over the thicker white line at the end of the straight.
Which is the finish line? If its at the end of the straight shouldn't they be starting from the same place? And shouldn't the camera be there?
If it is the line half way down the straight why doesn't the clock stop then?
Please help - its keeping me up.
