I dont agree. No one would try to break a 1x1 out of a 5x5. I hope nearly everyone would either first break 5x5 into 1x5 and 4x5 or directly into 5 times 1x5, which would only be 4 breaks. Therefore the rest would be broken in to each 1x1 with each 4 further breaks. Therefore resulting in 4 times 4 breaks, so 16 breaks total.
