Now to get from 14,000 to 7,000,000 would mean an average of 500 shares per account. That seems unreasonable

That doesn't seem that unreasonable to me. Everyone has 2^n great-great-grandparents, and that means a lot of cousins, uncles, aunts, etc. You don't have to go back many generations to reach a very large number of relatives. I think that's one of the cool things about genealogy.

Ok, that makes much more sense! I've done a tiny bit of genealogy, so I knew about the exponential numbers, but I misunderstood the sharing. Yes, I know the feature was described as "with relatives" but I was thinking of "with person". Yes, choosing to share with all relatives in one click would produce huge numbers.
