I've been stacking my split wood on pallets and for the most part they have interlocked on pallets that are about 3'X4" or 4'X10'. Started to load my truck up with walnut that had a stack date of 2/12. The splits seemed a little heavy to me so I took one of the interior splits, split it smaller and got a MM reading of 26%. Stopped loading the truck and went to my ash stack that was marked 4/12. Took a few readings and while many were around 20% quite a few of them were mid 20's+! Man, was I disappointed! Fortunatley the oak that was 3+ years was good to go! So, I guess I'll be mixing in the oak with what I have for this year and will be going with single row stacking from now on.
