Can someone explain to me how relay splits are obtained (officially)? What would happen if Asafa got the baton at the start of the zone vs the end of the zone? Would the split show up as the same? Are the splits just the baton splits?
They are when the baton passes the 100m mark of the zone. Also, I’d add that I believe the USATF splits from Beijing were from only 1 camera (as opposed to the 8 we use at National Championships) so the splits should probably be taken as +/- 0.04 seconds.
