Will like a better insight ot the Bank's Core.

Since the Bank has this unique self-righting SRC core with one single stable position. That no matter how you put the core it will always search to that single stable spot. I will like to know how the orientation of the SRC core is located inside the Bank. What I will like to know is to which side of the bowling ball is the single stable spot facing. Because in the 900Global tech video they say that no matter how you put the core on a flat surface it will move to that single stable spot. So inside the bowling ball the SRC core will try to stable it's self once it slows down and trys to set the direction of the bowling ball. And if you punch holes in the core, when doing the thumb, finger holes and balance hole if needed, how much more imbalance you can create. Inside the bowling ball of the Bank, to what side is the single stable spot facing using the pin, CG and Mass Bias as a guide.
