UPDATE...
So I just went out and tested the freshly cut stuff again. I was getting the same numbers, around 25% until I put more pressure on the meter and stuck the probes in a little deeper. The MC went up. On the fresh Oak, I'm now getting 31% and on the fresh Beech, I'm now getting 28-29%. I guess now I need to check all my other wood supply again with this new method of adding more pressure to the unit. I hope those numbers don't go up too.
Sorry, but either your technique or your meter are not correct. Freshly cut oak has way more than that. Any chance you can borrow another one from a friend?
