Help with Red Sea Copper Test Kit

So, as many probably know, the Red Sea Copper Test kit only reads to a maximum of 0.4. When using Cupramine in QT, the full dosage is 0.5.

The directions call for using 10ml of aquarium water and 6 drops of the reagent. Would it be a good idea or bad idea to use 10 ml of water with 3 drops, and aim for a concentration of 0.25?

I'm no chemist, so I'm not sure if it would even work!

Thanks for any advice.
