The sportscolour 600m time seems to exceed the AJC time by ~:
5% of rail position.
The AJC time appears to be correct.
Sportscolour uses underground sensors and obviously it wouldn't dig them up and reposition every time the rail moves. It claims to normalise the times to 200m but apparently doesn't bother to here.

JFC - I think you will also find that the racetime for the winner will also be different to that of the winner by 0.05 (5/100ths) of a second because the timer devices are in the saddle of the horse while the racetime is judged as soon as the winner's nose crosses the line.
As an example in last Saturday's Orr Stakes, Sportscolour have the race time as 82.36s and the winner's time Perfect Promise as 82.41s |
