This is generally true, unless the horse hits a rail or a rider is falling off, etc. There is a lot going on during a jump even after the horse leaves the ground.

Even with the D200 focus tracking and sharpness has not been an issue. As mentioned, timing often is.

Consider a screwball, a curve ball, a slider, a slow ball. That's why batter miss. My point being, this is not as simple as an object on a fixed trajectory. There are other things going on, even down to a rider's expression.
But you, and others here, are certainly correct in pointing out that single shot mode might provide a higher percentage of those 'just right' shots, and I will certainly give it a try and in fact, with certain jumps it is necessary, especially a head on shot. But in the end, it might actually turn out that I simply am not coordinated enough in which case "pray and spray" (actually a fire arms analogy that has more to do with aim than timing) might be the tool I require. A higher frame rate will improve odds
And what I have found is that my D200, at 5 fps or thereabouts, yields about 50%. Now that is across every jump, some of which are low percentage anyway since you can't be in perfect position for every jump.......particularly when it comes to cross country events. And of those 50% that aren't perfect, a good many are still okay and with an even greater number it is clear if there had been one or two more frames in the burst it would have captured a perfect shot. I think the D7100 will help with this, a higher frame rate would help even more but as mentioned, in crop mode I can get to 7 fps.
Another value, in this application, is that my daughter and her friends often do not care about a perfectly timed, perfectly sharp image. They like to see what is happening before, during and after the jump. In other words, they use the shots as learning/coaching tools. And again, a higher frame rate puts more images in that sequence. Now, when it comes to choosing a shot for their FaceBook page....they want the sharp, perfectly time one....of course.
Any way, I think 6-7 fps will suit my equestrian needs and should be beneficial in my motorsports and limited wildlife shooting as well.
