How is DRG weight calculated?

How often are DRG codes updated?
annually

How do you calculate relative weight percentage?
Calculating Relative Weight
- Look up the standard weight of a 15-inch largemouth bass from Table 1. Standard weight for a 15” bass = 1.8 lbs.
- Divide the weight of your fish by standard weight. Relative weight = 1.5 / 1.8 = 0.83. This bass weighs 83 percent of the standard weight of a bass the same length.
How do you find the variable weight?
The formula to calculate the weights is W = T / A, where “T” represents the “Target” proportion, “A” represents the “Actual” sample proportions and “W” is the “Weight” value. The weights can be easily calculated using a spreadsheet or with a calculator.
