I would say that test is not accurate at all.
you could try this method and see if it works for you.
First you need to have a progammed pendulum.
Then you can make this yourself just get a piece of card and draw and colour any shapes you feel drawn too to correspond to the 7 main Chakras and colours and dowse your pendulum over the symbol and colour for the charka in question and ask one of three questions to find out.
Example(1. Is my throat chakra too open?)(2.Is my Throat chakra balanced?)(3.Is my throat chakra blocked?)
You can ask all the three questions if you wish or just the one.
I find this method very accurate so long as the pendulum is programmed properly.
