Do you really, really think that CDs just don’t care about the horses, the riders, the sport?
Look up FEI safety data - it is published annually, on line - and see how much safety has improved in eventing. A simple example, FEI directions now say tables must have both a clear ground line and a slightly raised far side so the horse can read the question clearly. Tables used to be scary fences, ridden with caution. Now riders see them to be easy galloping fences. But falls at tables have nonetheless decreased.
Schooling shows are outside the remit of the FEI or USEA. It is up to individual riders, obviously, to decide if they wish to pay the cost of safety research and development (and all the other associated regulation, admin, staff and volunteers) at an affiliated show or take a punt on a “layperson” building a course. If every schooling show put in fall data then to whom? by whom? on what? where does it go? who pays for the analysis? USEA has standard measures so as to compare apples with apples, in a common format, at all levels, around the country. Statistical analysis is difficult enough without poor data also being fed into the system.
My gripe is that USEA doesn’t publish an annual safety report.
