Well I hope Brian's knowledge of the camera is better than his knowledge of horses !
You might try reading the review before embarrassing yourself with a gratuitous negative comment.
"Perhaps even more beneficial for understanding what can be done with this frame rate is to look at a visual example. Drag your mouse over the labels under the following image for a visual look at the 10 fps rate. Drag your mouse completely across all of the labels in 1.3 seconds to get an idea of the speed of the approaching horse – approximately 40-45 mph (64-72 kph). I know, the labels are a bit small for that mouse move, but this approach happened very fast."
She would have to be riding a top form Derby winner - on the flat - on good going - with a race saddle - riding weight less than 7 stone. As I said, this target would have been travelling towards the camera at 18 mph max.
Completely digressing from the topic, I think a horse can manage 30/35 mph at a gallop for very short distances. In this particular case, I wouldn't be surprised if Bryan asked his daughter to urge her horse fast towards the camera to model for the shots. You are referring to speeds held consistently over the course of a mile or so.
Widely believed to be faster than cheetahs in endurance races, the thoroughbred is the fastest breed of horse in the world, and can maintain a speed of 45 miles (72 km) per hour for a distance of more than a mile (1.6 km), making the Derby's 1¼ mile-long race the fastest two minutes in sports.
