If the center of the lie angle mark is at 1/4" from the centerline of the face, how many degrees must the lie angle be changed to move the sole impact mark to the centerline of the face?

To determine how many degrees the lie angle must be adjusted to bring the sole impact mark to the centerline of the face, it's important to understand the relationship between lie angle changes and horizontal shifts in impact location on the clubface. When the lie angle is altered, it affects the angle at which the club interacts with the ground, thereby influencing where the impact mark appears on the sole of the club.

In this scenario, moving the impact point on the sole from 1/4 inch off-center to the centerline of the face requires a specific degree adjustment. Research in club fitting reveals that typically, 1 degree of lie angle change results in approximately 1/2 inch of lateral movement of the impact mark on the sole of the club.

As the sole impact mark is positioned 1/4 inch from the centerline, which is half of the 1/2 inch movement associated with a 1 degree change, an adjustment of 1 degree to the lie angle will be sufficient to shift the mark to the desired centerline position. This understanding aligns with established guidelines in club fitting and swing dynamics, confirming that only a 1 degree change is required to achieve the objective.
