Abstract: Systems and methods receive first data associated with first launch conditions of a first golf ball after the first golf ball moves from a first initial position. The systems and methods determine a simulated landing position of the first golf ball, the simulated landing position determined based at least in part on the launch conditions. The systems and methods receive an actual landing position of the first golf ball, determine second data associated with an error between the simulated landing position and the actual landing position, and train a machine learning model using the error between the simulated landing position and the actual landing position. The systems and methods receive third data associated with second launch conditions of a second golf ball after the second golf ball moves from a second initial position, and determine, based at least in part on inputting the third data into the trained machine learning model, a predicted landing position of the second golf ball.

Abstract: A correlated set of golf club heads comprises a first and second golf club head. Each club head has a striking face, a rear surface, a top portion, a sole portion, a toe portion, a heel portion, and a loft. The striking face has a first plurality of scorelines defining a scoreline heel-ward extent and a scoreline toe-ward extent. The plurality of scorelines comprises a scoreline length LS1 being the lateral distance between the heel-ward extent and the toe-ward extent. The loft of the second golf club head is greater than that of the first golf club head. The scoreline length LS2 of the second golf club head differs from that of the first scoreline length LS1.

Abstract: A golf club head includes a striking face having a face center and defining a face plane, a virtual vertical center plane perpendicular to the face plane and passing through the face center, a sole portion, a top portion, a heel portion, a toe portion, a hosel configured to receive a shaft, and a loft, L, no less than 39°. A center of gravity is spaced from the vertical center plane by a distance, D7. A moment of inertia, Iyy, is measured about an axis extending in a heel to toe direction, parallel with a ground plane, and passes through the center of gravity, such that Iyy/D7≥527.4 g·cm/°×L−23,580 g·cm.
