When its an uneven non-fit your radius needs adjusting

Example 1

Posts 1,3,4 are good but its off at post 2, This means your radius is to small/tight, You should decrease your Y-Arm position to make your radius bigger/looser.
Or the tube is off the bottom 2, this also means your radius is to small/tight, and You should decrease your Y-Arm position to make your radius bigger/looser

Example 2

Posts 1,2,4 are good but its off at post 3, This means your radius is to big/loose, You should increase your Y-Arm position to make your radius smaller/tighter.
