Once it's in there it's in there, I've gone months without shooting and drilled center target on my first shot the next time I shot. After I got comfortable shooting recurves I moved to shooting progressively smaller targets until I could consistantly hit what I aimed at. First I practiced keeping them inside a paper plate, then a 6" plastic coffee can lid, then a 4" lid. After awhile I graduated to busting 2" Daisy Shatterblast discs that I pinned to the side of my 3-D target, at that point I knew that I was getting reasonable proficient. Having the 3-D at the bottom of a 20' deep sinkhole also allowed me to practice from multiple heights and angles.
