| Shaun,
I haven't used that test kit but my interpretation would be this...
You add one drop in the 8th step. If you don't get a color change to orange, you add another drop, mix it, if you don't get a color change to orange, add another drop until you get the color change your looking for. Count all the drops and read the chart.
That would be my guess. Let us know what you get.
Dick
