Experience and it's mentioned in every book I have read on the subject. I have noticed the more careful I am about not letting spokes wind up in the first place, the less pings I hear. In fact, when I build with bladed spokes there are no pings at all. Thus, my conclusion that the ping you hear is spokes unwinding.

Two different things. Stress relieving temporarily increases the tension in the spokes. This is meant to erase the "spring" from the bend in the spoke. It helps for long term durability of the spokes by increasing the fatigue life. Unwinding the spokes is a good practice otherwise they'll pop and ping when you first ride the wheel and it'll be right back in the truing stand.
