I've been studying disc flight for a while now, and one of the interesting things to come out of it is that the disc tends to pop into the trajectory that balances the aerodynamic lift and gravity forces, and stays there for most of the flight. The lift force changes as you change the angle of attack and speed of the disc relative to the surrounding air (air velocity=disc velocity minus wind velocity). Of course the disc slows with time owing to aerodynamic drag, and rising or settling of the disc also alters the angle of attack, so this balance is always a moving target. A disc tends to pop into this state of balance pretty fast (less than a second), and once it is there the only thing that can make it move up and down a lot is wind, which changes the lift and alters the balance. In fact, the time the disc takes to pop up or down in flight due to wind disturbances is representative of the time it takes for the disc to pop into a balance between lift and gravity when it finds itself not in balance.
