Absolutely; a multivariate linear regression test to determine the extent to which each of the earmark options tends to maximize total contributions should be run in advance, with a sample size (assuming 30 earmark possibilities offered four at a time in a variety of different languages and locales) of between 5000 and 30,000 donations.
Is that a practical number? How many donations do we get total per day?
