well, considering that it took me three years to call in my first fox, I'd say you're doing exellent! LOL! I didn't have access to very much info when I started, so I pretty much learned the hard way myself.
If you're calling in predators, you've crossed the first major bridge in predator hunting. The one thing I'd recomend is that unless you're using a shotgun, you'll do a lot better with a low powered scope when hunting at night with a spotlight.
You'll just have to adjust your calling set ups as you figure out what went wrong on each one. It takes time, and all the reading in the world can't come close to actual experience, which you'll get very fast if you put in enough calling hours.
As far as the distance between stands, there is no set rule for that either, as the layout of the land you're hunting pretty much dictates the distance you'll need to move. Here's the raw basics of how I decide how far my next stand will be.
If I'm hunting in open, fairly flat terrain, I'll start out calling on lower volume, and bump it up to pretty loud if I've not seen anything in the first few minutes. After I've finished my stand, because I know any predator for a half mile likely heard me, I'll usually go at least that far to the next one.
If I'm hunting thickets, or in steep mountain terrain(pretty much always here in SW VA), I'll stick with lower vlomues, and keep my stands closer together. I have at times only moved a couple hundred yards before setting up again.
Hope this helps?
