Okay, are you doing an intro test? (W/T) only? Has Sadie been in the indoor before?
I go with 62%.
The judge scores every movement on a scale of 0 to 10. 0 being not preformed and 10 being perfect. At schooling shows 5-8s are the usual range. 5-6 the most common. 7-8 very good scores. Rarely do you see a 9 or 10. 4's are common gimme points if you make a big mistake. Like say you're doing a test where there's a coeffiecent move (two scores for one thing) like right lead canter transistion and right lead canter circle. If you pick up the wrong lead, but you DO have a canter transistion you'll probably get a 4. You had a transistion, but to the wrong lead. See? Maybe?
Then, at the end are collective marks. Three are on the horse and are worth x2, gaits, impulsion, submission. One is on the rider and gets x3. So, these are big scores. Basically it's how pure and correct your horse's gaits are. Four beat walk, 2 beat trot, 3 beat canter. Not lateral in walk/trot, not pacey etc. How much impulsion - forward they have and how relaxed and listening to the rider they are. The rider mark is not necessarily equtation, though it does play a part, the big thing is effectiveness of aids. Your seat is an aid. Keep thy buttocks in the saddle.
