My first suggestion: DO NOT "plan on placing". That just puts huge stress on yourself.
Instead, plan on doing your best. Make it your goal to run a perfect pattern. If you place, super! If not, so what. You were focused on making a good run.
But keep in mind that pretty much everyone will never actually run a perfect pattern. There will always be at least one thing you wish you could go back and change. And that's the same for any barrel racer of any caliber.
Using myself as an example, there have been times at small shows that I have won the barrel racing, but in my mind, we had a terrible run once in a while. For those times I wasn't happy with the fact that we didn't have a nice pattern. Yea, sure, we won. But that wasn't my goal. Running a good pattern was my goal.
Don't put pressure on yourself to win. Go, have fun, trust in your horse that you've put so much time and effort into, and go have a good time and run a nice pattern.
