That is really how it use to be! Big gaits got you a few bonus points in the collective marks, and got you better scores in things like lengthenings, medium, and extended gaits. But otherwise, gaits was really only considered as pure and regular, or not… The old (AHSA/USEF) tests did not start every movement description with “quality of trot”, “quality of canter”, etc.
I do wish we went back to those days - it made dressage much more enjoyable and accessible. No one minded if the fancy horse got a few extra points in the collective marks - it just wasn’t such a huge advantage like it is now. Sigh, I can’t believe I’m pining for the “good ol’ days”…
