Hey,
it cuts off the lowest 3 bits. These lowest 3 bits are 001, 010, 011 etc, so
1,2,3,4,5,6,7
But cutting off only the lowest three bits, will result in 0..7 being 0,
8..15 being 8, while you want 0..4 -> 0 , 5..12 -> 8, etc, so 4 is added.
But Benjamin can prolly explain better hehe since it's his trick :)
