Copper level way off

[Jmas4]

I followed the cupramine instructions and after the second dose, it reads 1.2 on my hanna checker. What? Even if I didn't calculate the drops correctly, it shouldnt be double the end concentration of 0.5.
I just checked using seachem copper testkit and it reads between .5 .7 (color based is inaccurate) but definitely not 1.0 on the seachem test kit.
So what's happening?

If you have the seachem test kit... I would test it again along with the reference sample that is included. The sample is .5. Post a picture of the results, if you are able.

Agree, as well as test again with Hanna to make sure there wasn't an error of some sort.
