What is the formula?
Calculate the four factors.
Factor A: subtract 30 from percentage of pass attempts, divide result by 20.
Factor B: divide percentage of TD's by 5
Factor C: subtract interception percentage from 9.5, divide result by 4.
Factor D: subtract 3 from average yards per attempt, divide result by 4.
If any factor is greater than 2.375, lower it to 2.375. If any factor is lower than zero, raise it to zero.
Add the four factors together. Since no factor may exceed 2.375, their sum may not exceed 9.5.
Multiply the result times 100, divide by 6. The highest possible is 158.3. Tying the all-time record in each category would result in exactly 147.
