Speed

The top speed number (60) is the ideal thrown speed (in mph) of the disc. Thrown flat at this speed, the disc will hold the line. The bottom speed number is the distance multiplier (4.2). In this case, a disc thrown at 60 mph will fly 60 x 4.2 = 252 feet.

Fade

At a speed of 20% less than the ideal speed, this is the flight angle of the disc. In this case, at 48 mph, the disc will be flying 24 degrees left. (assuming a RHBH).

Turn

At a speed of 20% more than the ideal speed, this is the flight angle of the disc. In this case, at 72 mph, the disc will be flying 2 degrees right. (assuming a RHBH).
