Red oak split and stacked October 2019. Didn't top cover yet. (I'll do that this spring) had a dry warm summer and fall. I tested some splits to see if I could throw a few in mixed with my dry oak/ash stack. Small split 2.5 inches read 22%. Medium split about 3.5 inches read 25%. My bigger split 4.5 inches read 28%. These were all on the top and ends of my stack. I understand the middle of the stack may be a little wetter. Hopefully will be in good shape by next burning season. It will all be top covered in the sunniest area of my backyard that has good air flow. Splits were tested with wood inside for 32 hours at normal house temp 66-77°
