If you are interested in doing PSA, I will tell you there is a lot of bad training out there. A main problem is clubs training for the short run and not considering how doing so will cause problems at the higher levels. The sport requires a lot of control and like other protection sports, it is being made softer with poorer training of decoys who can’t catch a dog or be creative in trying to fail your dog, which used to be part of the challenge of the sport.
