Yes, but we don't know by how much and
that is why a calibration. But that is complicated
because club head shape, loft variation across
the face, shaft properties etc will determine
the bending moment due to gear effect eg. Trackman estimates
face based on AoA, Launch Angle and path primarily.
So , net-net we have an idea but we do not
know the club face angle at impact.
So then comes the question, how correct are
the ball flight law assumptions that initial
direction of launch is based on the face angle ?
Trackman assumes 85 deg face for initial launch.
Enzo and computer simulations show 60 percent
is dependent on face. So, I think this perhaps
has deeper implications on our assumptions and understanding of
ball flight physics.
