Absolutely the best practice, and with judo points it's almost impossible to lose an arrow. I've lost ONE over a couple of decades and literally thousands of judo shots. I've only broken a couple, using hardwood (yellow poplar) shafts. The main judo arrow I'm using now has been shot uncountable times, and I've been using it for several years. I've had to replace a couple of the fletchings, but the shaft is still in good shape.
I don't shoot at stumps or trees, because they can damage your arrow or cause the point to pull or break off. I shoot at leaves, sticks, pine cones, etc. There are enough small bushes and weeds with green leaves above the ground so that you aren't necessarily shooting at the ground. I like to pick an individual leaf on a bush that is a couple of feet tall, so that I'm shooting at the right height above ground to simulate shooting at an animal.
