Dye Solution Math

OK, the jar of dye says 1/2oz will do about 2 pounds of wool to a medium shade.
That would be about (I did some rounding off all through these
calculations) 14 grams of dye doing 907 grams of fiber, so that is
(14/907 * 100) 1.54% the weight of the fiber in dye powder. I'm
rounding that to 1.5 and making a 1.5% stock solution with 3.75 grams
of dye powder per 250mL (about 1 cup) of water. Then I'll use 100ml of
the dye solution for every 100 grams of fiber.
Does that make sense? Math people? I'm not known for my math skills.
