Yes - as I said in the other thread, scores in the 80's tend to be professional scores - in club level competition higher scores seem to be handed out very freely. Which is ok if you want to stay in those shows, but I know a lot of young riders who have become extremely discouraged when they go from scoring in the 80's with their club dressage days, to mid 50's to low 60's when they take the plunge into official/rated dressage competition. Its good to encourage riders at those lower level competitions - many combinations would score in the 30's if that type of work were to be shown officially, but that would be cruel to give those marks at a fun type show. But then it also gives that false sense of hope.
One kid I know gave up horses entirely as a result. She was getting high 70's to mid 80's up to novice level (1st level US??) with her riding club. She'd bring her photographer friend along, who would take thousands of photos and select only the few that made the combination look really good. Put them all over the internet, people commented on what a great rider the girl (teenager) was, what a talented horse etc.
The first time she went official, she was so scared that as soon as her horse pricked its ears, she burst into tears, started screaming and it took her poor coach over an hour to coax her into getting on and doing a test. She scored in the low 40's.
The poor kid had put so much pressure on herself by flashing these 'lucky shots' around, talking herself up enormously, that when she had to go out and ride in front of the people she'd been trying to impress, she lost the plot.
