The Four Factor
Set the first spring of the Super Gripper to level 4. Any level chosen for the second spring will result in a rating x10 for that level.
If you feel like getting nerdy about ratings, we have crunched the numbers! Each Spring 1 position has a consistent multiplier that can be used to calculate the rating based on the position of Spring 2.
Please note that the location of Spring 1 sets the multiplier, and the level of Spring 2 is used with the multiplier. Spring 2 must be at a higher level than Spring 1. For example, if Spring 1 is set to Level 8 then the multiplier is 13. Positioning Spring 2 at level 11 will result in the rating 11 x 13 = 143.
