What's the modifier on a trait that instead of providing a fixed advantage, becomes variable based on a die roll?

For example, let's say I had a Sorcery spell that provided +1d bonus to ST for all purposes. How much would that cost? I know that you can convert each +4 to a die roll into an additional die, so would +1d ST be the same cost as +4 ST (i.e., 40 cp)? (Not including any power modifiers such as sorcery's -15%.)

Also, what would a variable duration do the cost? Assuming that most Sorcery spells have a duration of 3 minutes, how would a duration of 3d seconds affect the cost of the spell?
