It all makes sense in the end, but it's still initially surprising for most people who are not aware of the explanation or suspect it. If you only know the partial percentages, then the total percentages would come as a surprise to most people. Obviously, once the weights are introduced, the initial surprise is exchanged for comprehension, but then a paradox is only a seemingly self-contradictory statement anyway, so I see nothing wrong with calling this a paradox. -
