One year when I was low on dry wood, I stacked some in the house with a couple fans blowing on it. I could see the indoor humidity rise, on the cheap plastic temp/humidity/pressure unit I have in the room. I did this two different times, for a total of about 2/3 cord. With small splits, the wood went from 25% to 20% in a couple weeks.
Yeah, why mess around?16" (I think) ledge running all the way to the wall, about 8' and stacked 4-5' tall can be a few weeks of wood or more. Now-a-days I cross stack the edge and get a bit more wood by going straight up.
