PRing means, "I've unlocked a new level of potential, not "I've hit my limit". I believe there's no true "genetic potential". Yes, there's varying time limits to make it as far up the totem poll as you can in each sport, but I don't think we can ever hit our limit until our biological clock literally starts atrophying the body. If health intact, progressive overload utilized, load management prioritized, system regulated, and sport specific qualities are developed, we will keep rising closer to the top!
