Your estimates of the donations needed to offset the harm to animals do not depend on welfare ranges (“welfare range” = “probability of sentience”*”welfare range conditional on sentience”). The values you use for the relative reduction in suffering for each group of animals only depend on pain intensities within species. You would only need to rely on welfare ranges if you were to consider donations to the best organisation instead of the best organisations helping each group of animals.
The calculator doesn’t funge different animals’ suffering such that you could donate all of your money to (for example) the Shrimp Welfare Project.
