It must be regional and climate determining the seasoning of oak. I have hot summers and cold winters, no snow. I have oak, Querces Lobata- white, red or black I don't know, we call it valley oak, other native oaks are blue oak, live oak, or pin oak. These native trees get punky in the heart wood at the base and fall over. The native semi-arid climate they prefer, and over watering of landscape does them in. I just went through 3/4 cord that was cut fall '11, split and stacked early spring '12. Maybe it could have been better, my Harbor Freight MM said anywhere from 18%-24%. It ignites quickly on hot coals, burns hot. The ignition test is supreme.
