Mare performance test?

Oh dear, there will be a mare performance tets in october and I'm thinking about whether I should let her take part of it or not.

Maybe you're wondering what a mare performance test is and what kind of advantages it provides you.
To get a mare registered as a broodmare you only have to take part with your mare at the studbook entry at which mares are shown at hand and their walk and trot as well as their type and conformation is judged. Mares between 3 and 4 years are shown in freejumping and in free canter in the indoor, too.

But if you want to get a foal of the mare get the allowance to be keured, your mare needs to be tested even more, especially their skills as a riding horse.
Plus the foals of a succesfully tested mare will get a better grade at a foal show. Succesfully tested means with a grade of 6,5 or better.

Now I'm wondering wether she'll get this grade or not. In a way I think she'll absolutely get a grade better than 6,5 because she even got a 6,7 in her studbook entry where she could not show her strenght, freejumping, because she's already 15.

In the performance test I will have to ride her in dressage and the judges will give grades for walk trot and canter and her rideability. Afterwards one of the judges will ride her and give another grade for her rideability. Her conformation and type will be judged again afterwards and then her gaits will be judged again in the indoor when she runs free. Afterwards they judge her jumping ability and technique in freejumping.

I think she'll get good grades for jumping and rideability but not more than a 6 for her gaits I think.... well... I have to ask my trainer next week wether she think it's worth a try or not.
And I have to ask her wether she thinks I'm good enough to present her under saddle at the test. ;) ;)
