Number Ratings on Innova Discs

So what the hell do those numbers mean on Innova's line of discs?

There are four numbers on each Innova disc. Sometimes they aren't actually on the disc but one can find these numbers on Innova's website (innovadiscs.com).
(All of the numbers will be described as if it is a right-handed thrower, throwing backhand)

The first number represents the speed at which the player must release the disc in order for the disc to act the way it was intended.  For example a disc with a rating of 9 is not as hard to throw as a disc with a rating of 13 (Innova's most difficult discs to learn to throw).  So if you have a monstrously powerful experienced throw, go with a 10 or higher, if you are just beginning or have a more finessed throw, stick with a 9 or below and work on technique before power.

The second number represents the glide of the disc or how long the disc will remain in the air.  Think of it as the disc's ability to float. Something to keep in mind is that the disc will only act and glide at its number if thrown at the proper speed for the disc.

The third number is the disc's tendency to go right after it is thrown. A disc, such as the Valkyrie (9,4,-2,2) will tend to go right a smidgen and then come back in left.  A disc with a rating of 0 in this attribute will not go right on its own but must be made to go right by giving it an-hyzer when one throws it.

The fourth number represents the discs tendency to go to the left. The Valkyrie is at a 2 so it will go left but not that abruptly. There is a disc Innova just released called the Ape with specs (13,5,0,4). This disc will not go right unless you manhandle it to the right.

The fundamental thing to keep in mind is that when you are beginning is to find a disc that natural counteracts itself. This will ensure straight, long drives.  A person throwing an Ape or its 9-speed alternative must actively create the right to left, whereas a person throwing a Valkyrie or its 13-speed counterpart must only focus on the speed of the throw and keeping the disc level as it is released. The Valkyrie's 13-speed counterpart is called the Groove and is a fantastic disc as well. (I have two in my bag)
