My unofficial xc stats:
64 XC starters (one individual rider from China w/d before XC).
57 finished on a number (including the Italian rider subbed in after dressage who is not in the individual results).
10 riders were double clear - would have been two more but both got flag penalties.
4 missed flag penalties awarded.
One horse fall - Portugese rider at fence 3.
Two rider falls - Equador and Germany.
One rider pulled up by the Ground Jury - Czech.
One frangible device activated - Finland.
One horse retired on course due to injury - AUS.
One ambigous - Poland. Fence results show as Retired at 10A, but this was after refusals and the summary shows an E.
And beyond that 10 refusals/run-outs among riders who finished.
All in all, quite a safe day of sport though the one horse fall was scary looking. The course tested the whole field - from top to bottom. In that respect, I think the course designer nailed it. He also did a fabulous job of utilizing the venue with stunning visuals, and the builders knocked it out of the park.
