I don't know what Hoadley says, if anything, about warping while drying. I have both of his books and it has been a long time since I last consulted them. Another reference would be the Forest Products Laboratory. My experience is with mainly local woods and weighing them as they dry. When the data is plotted, it is fairly obvious where the free and bound water loss occurs. I could be wrong about warping, but it seems like splitting in white oak occurs rather quickly after it is cut. I'm not certain about warping since you mentioned your experience, but it would stand to reason that loss of bound water is more responsible for warping than the free water would be.
