With our Force 5 if the wood is split too fine or is too dry it burns too fast. The extra heat simply goes up the stack. I've never measured the moisture content but I understand 15% is optimal. It allows you to dial the primary air up and down to control the burn rate.

When we did the demonstration boil for Lapierre (our unit was the first in Ontario) Rejean L was there to run the evaporator. We had a bunch of thinly split and bone dry poplar and basswood for the demonstration. After a short while he told us - get me some wet wood because this stuff is going up like gunpowder! We had some unsplit basswood that was laying on the ground that we put in and the boil rate went up because he could control the gasification with the blowers.
