I also finish in one session including the bottom. One thing I have found is that if I pour Antique oil on the inside and slosh it around till it won't soak any more in most times it bleed thru to the outside. Then I flood the outside till it won't soak anymore in I don't seem to have much if any warping. Don't know for sure but I am guessing the oil displaces the water left in the piece. Since I started doing this I haven't had a piece that has warped to where I can't do anything with it.
