Well, towards the end of this year I was burning some red oak which had been c/s/s right around two years. I tested some random pieces and I believe they were 21, 23 and 27%. The 27% one could have came from the bottom of the pile were they were just stacked on the ground, I don't know. I then quite burning from that pile. I have 7.5 cords c/s/s under a lean two on concrete (open on 3 sides) for roughly 4 years but are stacked very close together (before I knew any better). I thought the stuff stacked in a single row in the open may be a bit better than the stuff stacked tightly under a roof. I still don't know what moisture level I'm going to find once I get more into the middle of the lean two stash. This is why I opted to use the stuff in the open.
As far as burning. I didn't notice any difference, however this was my first year burning, so I have nothing to compare it too either. I would think the wetter the wood the more moisture you will be pushing out the back if your burning appliance burns front to back.
If you've got Oak in there, you're in a race against the rotting sapwood as well...
Came out at the top end of your initial guess. I like the empty wheelbarrow in the pic; That's a lotta wheelbarrows full of wood! Kinda dwarfs the 4-cord stack we've got going at my BIL's so far. A lot of that was small, dead trees (stuff he can burn this fall.) Takes a while for it to amount to much. I won't be working steady at it, but I'll be messing with wood all summer, trying to dodge the real hot weather I hope. Enjoy that gorgeous WI summer...you've earned it. 
I, too, am unsure about how the Oak I'm stacking now will dry. I just began stacking 3 rows wide on pallets. I'm way ahead, though, so I'll be OK. Just wondering how much difference in drying speed between the new 3-row blocks and the former 2-rows/pallet with air space between rows. Where did you get the EPDM, did you contact a roofer? How wide/long are the chunks when you get 'em? My covers are about shot and I really should get some new ones on this year...
So far, I haven't ever gotten a lot done in the winter, which shouldn't be hard here. Luckily I can handle heat OK; I just slow down and drink a lot of water. The only thing that saves me is that it's shady in the woods and the yard where I stack. Hopefully, I get all my burning in-laws 3 yrs. ahead this summer, then I can cruise. I'm just dropping, bucking and hauling the wood for them, they split and stack. For my stove, I've got several years stacked, like you do. It's a good feeling, ain'a? 
I loved the post, it shows some great engineering humor (and no, it's always an oxymoron).
