You are not being unrealistic about moisture content, just a bit unrealistic about what wood sellers sell. There are only a few that will guarantee truly seasoned firewood. For others, seasoning can mean one week or 6 months. The inconsistency of the first ash delivery could be because the wood was split into a big pile. Ash usually dries quickly, but if it sat on the ground at the bottom of the pile it will take much longer to dry. There is a seller south of you that will guarantee dry wood, but they are sold out now. It's late in the season.

Start getting a couple years ahead on your firewood stash and you can go ahead and buy fresh cut at a lower price. In the meantime try to buy faster drying wood (ash, soft maple) and test a few splits off of the truck before they dump the load.
And clean your chimney once for every cord burned while burning this less satisfactory wood.
