Ah, great! I think it would be nice to offer different aggregation options, though if you do offer one I agree that geo mean of odds is the best default. But I can imagine people wanting to use medians or averages, or even specifying their own aggregation functions. Especially if you are trying to encourage uptake by less technical organizations, it seems important to offer at least one option that is more legible to less numerate people.
