OK....the title is trolling for a reaction.
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").
Or....do I misunderstand what OAT is?
