This field contains the weight of the option value. This field is used when weighted option values are calculated for recipes . The option value of the ingredient with the highest weight is the calculated option value for the recipe.
Example: The Nuts attribute has options values Yes (weight 2), No (weight 0) and Maybe (weight 1). A recipe has three ingredients, one with Nuts-Yes, one with Nuts-No and one with Nuts-Maybe. The calculate process returns the option value of the recipe ingredient with the highest weight which is Yes in this case. The calculation process stops when it finds an ingredient with the maximum weight possible.
