But, if you look at the physics of throwing a disc, you impart almost no torque (rotational force) on any axis of the disc except revolving around the Z axis (the injection dimple in the middle of the disc).

OAT means Off-Axis Torque. It means your throwing motion is imparting spin to the disc in an end-over-end manner (or side-over-side).

If you compare the forward velocity and on-axis rotational velocity imparted on the disc at release, it will absolutely dwarf any rotational velocity that is off-axis. The only thing you see as a result of OAT is wobble or flutter. OAT is almost completely immaterial to how a disc flies.

OAT is an inaccurate term that needs to go. What really needs to be talked about is the plane of the disc upon release (or the "hit"). I misunderstand what OAT is?
The plane of the disc is important, but if that doesn't match the plane you're pulling through on you have issues. That most often happens when rolling your wrist as you throw. It causes wobble, decreases distance and can make for unpredictable flights if you're not in control of it. Sure, that torque is a small percentage of the total torque applied, but I think it's disingenuous to say it has almost no effect on the discs's flight.
