Chunyi Lin touches on this subject a bit in his book, "Born a Healer." He even has a chapter on it. He doesn't really go into specifics, exactly, but he says that practicing Qi Gong could make you operate at your peak in whatever area of your life you choose. It's all where you focus your energy. For me, personally, as an artist always trying to create from a much greater place, I always connect with the Master's energy, the universe's energy before I work on a piece and have felt quite satisfied with the results. My suggestion would be to enhance your visualizations by connecting to the universe's energy beforehand as this directs this powerful energy into your performance and will will help you to relax deeply.
This is a great question, BTW, I also would like to know if there's any more info written in this area since I know the course focuses more on healing. I think in the later levels, though, levels three and four where you will be focusing more on opening the third eye which can only enhance your visualizations in a more profound way, it can be easier to see how to direct this energy towards peak performance.
