Although I may not be a GM class shooter, I am an expert at continuous improvement. I am a Manufacturing Engineer, so I break down processes and find ways to remove wasted motion. I just don't have much natural talent.
Here is the typical cycle for improvement:
Plan: Have a concise plan of action, know where you need to be at any point in your production cycle. In this case it would your game plan for the stage. Run this in your mind until you have it down pat.
Do: Run your game plan in real time when the buzzer goes off. Hopefully your mind is clear and you are running on subconscienceness.
Check: After the stage and while preparing your mags for the next stage, think about what you did right and what went wrong. Single out the most important area that needs improvement and write it down. Include it in your game plans
Act: Now re-run the stage in your mind with the correction in place. Your mind will have the positive reinforcement it needs for your next stage by running the stage perfectly.
Prepare for your next stage......
Plan, Do, Check, Act. Repete, Plan, Do, Check, Act. Repete.............
Man, I wish I would have found this sport in my youth......but, I can make little improvement everytime I shoot.
