No.
The game changer is Prelim and up. The courses become rather complex and become a rat race.
The study has focused on 2 problems, they are very basic, down hill or up hill. They are a very important problem, because of the way a horse jumps, the collection and terrain can help with that, up hill.
But riding those very complex courses is influenced by every jump, every combination and the sequence of them.
If a rider just mastered a rather difficult combination, or a collection of combinations ( exhilaration, hippieness, yeeeeeeeehhhhaaa ) and than gets offered those rather easy let down jumps, big spreads, before the next wild test comes. Is the course design, the philosophy behind it, part of it. The up and down in demand on the rider, loss of focus.
I am not putting you down, ok. I am know to bash everything below training. But if you have ridden only to training level, you need to sit down with a dead honest, pragmatic person and do some course walks, not the for show walks and explain to you how complex the upper level courses are. Most jumps, have a jumping window of less than 2 feet, combinations less than a feet, if you miss that window it gets rather messy. You have to be spot on, 12 inches, get the ruler out, or 24 inches.
Every single one of us who have ridden upper level know how important rhythm is and than push it and push it. If there is a hick up, that so important rhythm goes, how fast can we regain it. Go from the moment when your skin burns, that’s how it feels, to were we are again totally relaxed and laser sharp focused, confidant push the limits.
We are not riding a truck. The animal between our legs takes in all our feeling emotions. It might save our ars, but if we do not get over that skin burning rather fast, it is lost. Or if we lost focus for a moment because it is let up jump time.
It is a very complex subject.
Me thinks the problem aint the jumps, but how we use them.
Me thinks, with out any data, the let up jumps are the problem, not their design
