There are many options for using the "Plus 2" diamond system. Calculated "track lines" of aim at 7-7 and 6-6 and corresponding "parallel shifts" as needed, require slightly less sidespin while calculated "track lines" of aim at 4-4, 3-3, and 2-2 and corresponding "parallel shifts" as needed, require slightly more sidespin due to the compression differences on the first cushion of contact. Normally, these sidespin adjustments decrease or increase in quarter tip increments from the 5-5 application
