I have been shooting uspsa just about a year and half.. Just turned 50, I'm on the verge of making master class in limited division.. What's helped me the most is, the obvious, lots of dryfire... , movement is key , this allows me to know where I can make up time.. I. E shooting on the move where I know I can execute excpetable hits.. But the most important one for me is come up with a my own stage plan that I can I execute on a dime once once I visualize the hell out of it.. Visualize, visualize, and visualize..
