Can I set up scoring tiers for decimal categories like yards-per-attempt and completion percentage?

No. It's not possible to configure a contiguous set of rules that cover all possible values. For example, the following rules won't cover any value in between the defined endpoints:

• 1 extra point when completion percentage is between 30-39
• 2 extra points when completion percentage is between 40-49
• 3 extra points when completion percentage is between 50-59

In the above example, decimal values between 39-40 and 49-50 are not covered.
