Okay, I'll play. Moving from your center imparts a certain conditioning there. One of the giveaways of those who really don't get it is their non-conditioned loose fat belllies and stiff bodies, which rock their frame on to their heels and outer edges of their feet when they receive load- which defies any real capabilities to use dantian beyond a hopeful intellectual curiosity. It's good to get your hands on some accomplished people to see and feel the difference.
