Unless independently wealthy, developed practice sessions to maximize time,ammo and effort. If I practice barricade at 50 there is no need to do it at 25. For kneeling I drop straight to both knees and shoot offhand un supported so if I practice match 4 I am also practicing kneeling match 2. I never practice 7 yd line because if I can hit it at 15 I can hit it at 7. Based on the above I shoot match 3 and 4 with a 15 yard line thrown in. Try to finish match 3 with a 6 in 12 at 25.
Watch the top shooters and copy what works for you. At the heron 1500 championships (long ago)jerry Eason and I had crowds watching us and we did a question answer after we finished, MOST top shooters will give tips and talk as long as it is timed to not interfere with their shooting,hope all is going well
