Steel Classy was an Appendix QH that Jennie Jarnstrom ran around Advanced and Rolex when it was a 3*. Then it ran around P/I with other riders.
I evented my 88% foundation QH at Novice. My results would be in the USEA archives. (He’s 26 now). Not sure if you want “dated” statistics.
I see the rule change proposal to have AQHA recognize eventing is once again before the English and Dressage Subcommittee at the 2019 AQHA Convention. Another proposal had previously been approved by the Subcommittee and the Show Committee only to be nixed by the Executive Committee. Does anybody know who submitted this rule change proposal?
