If 50 sells 300 units and 60 sells 200 units, is it logical to say both combined would sell 250 units? (No)

Like I said, that's assuming both combined would be more than one SKU. Perhaps because there are two, the number of each SKU is reduced because one takes away from the other. So: Two SKU = 100 + 300, placing it at 50, but one SKU could be at 400 because that is all that's available, also placing it at 50. Can you see what I mean? We can't possibly know how many each are selling so (for me) the best option for now is to place the position midway between the two.
