Moisture levels vary with location and time of year. Weight will also vary with a dry stock gaining weight if the weather turns wet for a time. Most areas of the country will find 12% dry with desert areas being 5-7% following a dry spell. That same wood will go closer to 20% if the wood is moved to a very wet area like the NW coast. Once it is dry, wood should be allowed to stabilize which will take at least a year depending on local humidity. Your stock obviously was not really dry. Accurate weighing over time is a good indicator of dryness.
