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?
As I understand it, IF I understand it, this is basically right. but it wouldn't have to be 90 deg off-axis to be off-axis. I think someone on here described it once as, imagine you're spinning a quarter on a toothpick with your finger. If you don't spin exactly perpindicular to the toothpick, you're applying some off-axis torque, causing in this case the wobble.

I'm not sure I'm grasping what you're calling the disc plane vs. release angle.
