 'DS (coded dictionary size, 1 byte)'
-     Lzip divides the distance between any two powers of 2 into 8
-     equally spaced intervals, named "wedges". The dictionary size is
-     calculated by taking a power of 2 (the base size) and substracting
-     from it a number of wedges between 0 and 7. The size of a wedge is
-     (base_size / 16).
+     The dictionary size is calculated by taking a power of 2 (the base
+     size) and substracting from it a fraction between 0/16 and 7/16 of
+     the base size.
      Bits 4-0 contain the base 2 logarithm of the base size (12 to 29).
-     Bits 7-5 contain the number of wedges (0 to 7) to substract from
-     the base size to obtain the dictionary size.
+     Bits 7-5 contain the numerator of the fraction (0 to 7) to
+     substract from the base size to obtain the dictionary size.
      Example: 0xD3 = 2^19 - 6 * 2^15 = 512 KiB - 6 * 32 KiB = 320 KiB
      Valid values for dictionary size range from 4 KiB to 512 MiB.
