I'm really confuse about my calcium test reading in Salifert.

I bought this calcium test kit and I heard this brand is the best so I try it out, but I can't even understand how to work with it. I did a low resolution test by using 1/2 scoop reagent 1 and 4 drops of reagent 2 and add slowly .01ml at time until the color turn pink to clear blue. My results is the position of the syringe piston is on 0.06mL so do I calculate by (1-.06) x 500 x 2? give me 400ppm? or how does it work?

An easier way is to get the ppm reading from the syringe at the low resolution and double it, so if you wind up with .6 in your syringe and your chart says 200ppm, double it and you get 400ppm, which is excellent!
