Geez, first you beg for mercy, and then you expect advice???
Tell you what. If you're hitting, no wait......
If you're surprised when you miss a skill in a routine because you almost always hit, you're doing fine.
If you can get through your routines without feeling like the next skill is coming too quickly, you're doing fine.
If, in addition to your required routines, you're working mount plus next two's and last two's into dismounts, and any elements that aren't yet "like butter", you're doing fine.
There's a lot of ways to get to "doing fine", my way works for me.... but may not work for another coach. The bottom line is to have confidence in your skills and your ability to present them on a moment's notice, ideally, as a piece of human art in motion.
I think you either get that already, or just did. So try to apply that standard to those three routines and the skill work done before and after, because if you try, and continue to try, you're doing fine.
