Most stove manufacturers who actually put the info in their manual, suggest 20% or less. Having typed that, they also say that you should "season" wood for 6-12 months before burning. That's fine for some wood and areas of the country, but won't work for anything but soft hardwoods, and Pine around here.
When I started, the wood was really wet and didn't burn well...no MM needed to tell me.
The wood has gotten drier and burned better because I got ahead a little more each successive year.
Strive for that and be happy.
Pine, Poplar, Spruce, and others will dry well enough to burn in 6 months (longer is gooder), soft Maple, Ash take a year or more, Oak.......well, Oak is in it's own category.
No experience with BL, Hickory, or others.
I had nothing but Oak at first. If I'd known better (I didn't), I'd have gotten a bunch of Ash for the 2nd year.
The 1st couple years are the toughest. If you can learn early that wet doesn't burn, you've come a long way, baby.
