Default Gh test issue

I'm using a Nutrafin Gh test which requires adding drops until a visible color change happens. With this test, the difference between drops is a little over 1 dH. If I double the amount of water from 5ml to 10ml and count drops until color change and then divide by two will I get more accurate results? Are there Gh test kits out there that measure more accurate than 1dH increments?
