This is often a trial process and learning how you respond personally through a few rounds. You're pretty well on point though.
Just a few suggestions:
-A greater build up, 5's in the 2-3 bells below the test weight.
-A double or triple with the weight higher to prime your nervous system.
Either or both, take a generous rest (5-10min) before the test itself.
Film the test to make sure your ego didn't force a bad rep or two at the end. Look professional!
Hope that helps, and good luck!
