You're right. What is strong for a martial artist will be different from what is strong for a crossfitter, which will again be different from what is strong for an adult recreational football player. I really have no idea what these numbers are.
I do have an idea of what is strong for the gym population as a whole, and that is described in a previous post. This does, of course, favor those who specifically practice strength training, but that is exactly how it should be. Those who practice playing soccer will be good at soccer. Those who train in martial arts will excel there. Those who train for strength will be strong.
