Hi -
If you click on this link to the equestrian section of the official website, clicking on the + sign suggests that they revert to their own individual scores.
But I have another question: I could not watch the last Olympics (not in the country and no tv) so I can't remember if the individual medals are always allocated after a second, individual jump off.
I thought - may have a faulty memory, though - that the top three individuals used to get the individual medals with no second jump off. Has it changed in the last couple of Olympics?
