Supply Size (& thus Usage) might not match your actual size. For example, both Caelians (Size 3) and Hoburgs (Size 1) are Supply Size 2.

The following applies to Supply Size:

	Size 1	Size 2	Size 3	Size 4	Size 5	Size 6
	0	1	2	3	4	5

Note that this is not told to you directly, unlike Supply Bonus or Gluttony.
