I think some of the points are not accurate. Trumpet hardware is metal and therefore relatively constant. The "resistance" of the horn allow us to dispell air while playing (we need fresh air at regular intervals to stay alive). This is faily critical - too much resistance and we can't get rid of the air, too little and we can't phrase properly. Both situations would limit our capability to deal with anxiety during playing. Hardware decisions need to be solved well before the audition (be careful when using a cornet or rotary valved trumpet borrowed for an audition). Solid practice of the "mechanics" (breathing, basic tone production, range, speed, endurance) gives us room for error in judgement/anxiety as well as a sound basis for concentrating on making music while playing.
I try to deal with anxiety BEFORE putting the horn to my face. Yoga is one very good way. Train wrecks can't really be practiced, so experience and luck are important here. Having enough air can solve many of the problems experienced by brass players. Using the air sensibly can increase our margin of security.
This could turn out to be a book so I'll stop here........................
