getting into position-this is all figured out on the walk through. find a spot on the ground that can't be erased or moved and make it your mark to hit as you approach the barricade. if you don't have a mark to eye ball as a visual reference while running up to the barricade you are much less likely to hit where you need to be/want to be.
getting on target more quickly- again, when doing your walk through, knowing where the targets are and how many of them is great. but as few targets as there are and with a written stage description i think you can spend more of your brain power/memory on remembering where your gun needs to be from one side of the barricade to the other in relation to the target. find a scratch, smudge, bullet hole or whatever so that you know pretty closely where the gun needs to be to be on the -0 as you present it around the barrel or wall or whatever.
also, move your eyes to the target before you move the gun to it.
dry fire set ups, with a timer, in your house or garage. 3' feet to the side and 3' back from a bianchi barricade. set targets up and a par time.
transitions- do the stuff i just mentioned above. this is one thing where you can really increase your ability with dry fire as it is really about your visual ability and not your shooting ability.
splits- bill drills, bill drills, bill drills. 7 or 10 yards. 6 rounds. anything out of the -0 means you failed. i will also give away one of my top secret tips for better splits. i set the metronome app on my phone to "click" at a pace that equals a click every .20 of a second, which is a pretty good split. then i will pull the trigger on my SIRT pistol for as long as i can at that pace while on one target at first and then transitioning between targets.
there ya go!
