Not knowing your pap or what that works out to be in a dual angle measurement, the result will be a ball that reads the lane slower is and smoother on the back compared to a ball with the mass bias closer to the vertical axis line. Pin up is also a very subjective measurement because it's height and distance from the pap matters too.
Ok, I went on a bit of a tangent. The higher the number for the intermediate diff, the more midlane read and thus more forward motion through the pins. .020 will be comparable with most other strong assyms on the market.
