I shoot a recurve like you do, and have a dual method of practice.
First is what I call my "form practice". That's where I stand relatively close to a target (5' to 10') and I'll close my eyes and visualize nothing by my form. I will do this for a few moments and then slowly let down. After a few times doing this, then I'll shoot an arrow. I'll do about a half dozen of these. At that point I'll either continue my "regular" practice, or set the bow down and do something else. This is done inside on my basement range.
Secondly, I will do a regular practice....shooting at various targets from different ranges and positions. Most of this I do outdoors whenever possible. I have a 3-D deer, and various empty plastic jugs strung from tree branches and bushes around my place. Virtually all of this is done with Judo points. When the weeds and grass start growing, I do at lot of shooting at weed heads and the like. I also like to incorporate a lot of long range stuff......40 to 80 yards. I will never shoot at game at these ranges, but if I can group at 50 yards, even if I'm low or high, then I figure that's a good indication of my form.
