I've cut and split green red oak to 16 inches or so and 70-75 pounds sounds reasonable for a two foot round.
Fresh cut, 2 weeks ago, dead standing chestnut oak. Most of this load was the tree that got struck by lightning, I think 2 years ago. Lol, nope. Closest wins.
Dead standing I change my WAG to 50 pounds for a 24 inch X 12 inch round. That's probably a little light considering bark is still on and it's probably at 25% or so.
