I'm with Lumifer on this: even though what EAists are supposed to care about is basically total money given (assuming it's given as effectively as possible), that doesn't mean that hypocrisy of EAists is a function of total money given.

Having said that, just eyeballing the data seems sufficient to demonstrate that EAists are (at least according to self-report) more generous than non-EAists in this population, and I bet any halfway reasonable analysis will yield the same conclusion.
