The nature of the coaching and hierachy beast in Aust is to acquire the best athletes to justify their jobs. I myself have coached national jnr champs in sprints/jumps and hurdles, coached snr national winners and coached a masters world champion in varied events. And true the good athletes were acquired from me (all went backwards). Some were offered OAP funding to leave.
The 22 rep theory is like saying a 110mH guy should do the same principle but add a jump squat or fwd lunge every 4th rep.
